Nidez 0 #1 July 23, 2007 Italian Wingsuit championship 2007 ------------------------------------------------------ sorry 4 the English, I used Google Translator.. ------------------------------------------------------ WHERE and WHEN The contest will be from 21 to 23 September in Skydive Tortuga Arezzo. http://www.skydivetortuga.com/ REGISTRATION The championship will be a social contest, so the registration will comprise also the association to the a.s.d. FRECCEtte TRICOLORI. To register please put a Bank Transfer of € 100 to: ABI 05188 CAB 21501 CC. 1976 intestated to a.s.d. Freccette Tricolori indicating of the motive of the deposit “Name and Last name - associative Quota and ticket reservation for the contest”. The participation quota includes: - the 3 ticket of contest (minimums, can be jumped more if it is desired) - the association to a.s.d. FRECCEtte TRICOLORI - the T-shirt of the event - the reservation of a bed place. The registration is understanding which deposit and will not come refounded in case of absence of the competitor. The social ticket from right to participating to all the TRICOLORI events of FRECCEtte always paying the ticket from “associate of the DZ” without therefore the classic upgrade of 2 or 3 €/ticket that it comes usually applied to the foreings of the center. TRAINING During the first 3 week End of September training and navigation camp will be kept on the contest DZ Skydive Tortuga, Arezzo. THE CONTEST You need to do 3 jumps as minimum: one for discipline: Time, distance, speed. Jumps will be measured using Garmin GPS devices http://www.garmin.it/ and Paralog Software http://www.paralog.net/ a frame of 1500 meters of altitude (from 3500 to 2000) will be used. Every Jump can be repeated as many time you wish. It will be maintained the best result. Before every jump you have to declare which discipline you are jumping for. Since flying a wingsuit means in first instance respect the fight path will be assigned a cone of +/- 20° on the predefined route, exiting it will be judged null and the jump have to be repeated. POINTS Points will be calculated in the end of the competition in a % system based on the best performance. Let's do an example: Donald Duck is doing the best time, (in Example) 78 sec that's equal to 100 points. Mickey Mouse is doing 52 seconds (never seen a mouse flying more than a duck !! ;P ) and it's equal to 78:100=52:x so x=(52*100)/78=66,66 points. In the same way will be evaluated the distance and speed run. The final score will be the sum of the 3 best individual runs. Summing the % points of time and speed discipline you will have a score that is equilibrating the weight factor, while the distance factor is done by the aerodynamics of the flights and bodies. SCORES They will come created two scores: national and the international one. The separation of the scores has been necessary from the clear intention of promoting the activity of the Italian bats without excluding from the competition foreign hosts. The organizers will only participate to the international score for the same reason to leave space the emerged bats Italian. PRIZES: It classifies National - 1° Place: - Aerial Ticket in order to go to Cochstedt or Stupino or Marl in 2008 and to participate to one international competition like Italian delegation. - TonFly Helmet to choice http://www.tonfly.com/ - Reduction in price 50% for one Bird-Man Blade http://www.bird-man.com/ - Licence for the Paralog software with which analyzing the own flights on google Earth http://www.paralog.net/ - Gloves Phoenix Fly http://www.phoenix-fly.com/ - T-Shirt Bird Man - T-Shirt Phoenix Fly - T-Shirt 90Percent http://www.90percent.it/ - 2° Place: - TonFly Helmet to choice - Gloves Phoenix Fly - T-Shirt Bird Man - T-Shirt Phoenix Fly - T-Shirt 90Percent - 3° Place: - Thermal Sottotuta TonFly - Gloves Phoenix Fly - T-Shirt Bird Man - T-Shirt Phoenix Fly - T-Shirt 90Percent - Last classified: - 5 Ticket near Skydive Tortuga in order to train themselves and to gain the next edition! ;) - T-Shirt Bird Man - T-Shirt 90Percent It classifies International: - 1° Place - Helmet Stinger by Phoenix-Fly - Licence for the Paralog software - Gloves Phoenix Fly - T-Shirt Bird Man - T-Shirt Phoenix Fly - T-Shirt 90Percent - 2° Place - Thermal underware TonFly - Gloves Phoenix Fly - T-Shirt Bird Man - T-Shirt Phoenix Fly - T-Shirt 90Percent - 3° Place - Gloves Phoenix Fly - T-Shirt Bird Man - T-Shirt Phoenix Fly - T-Shirt 90PercentMarco "Pazzo" Pistolesi pistolesi.marco(at)gmail.com Quote Share this post Link to post Share on other sites

Summing the % points of time and speed discipline you will have a score that is equilibrating the weight factor, while the distance factor is done by the aerodynamics of the flights and bodies. Yo! Adding time and speed points calculated as you describe will produce nonsense scores. If the maximum time across the group of jumpers is tmax and the maximum average speed is vmax, then jumper A will get scoreA = 100*tA/tmax + 100*vA/vmax If jumpers A and B have the same "quality" (aerodynamics-wise), but jumper B has wingloading N times higher than A, his time will be tB = tA/sqrt(N), speed vB = vA*sqrt(N), so he'll score scoreB = 100*tB/tmax + 100*vB/vmax = 100*tA/sqrt(N)/tmax + 100*vA*sqrt(N)/vmax So in general scoreA is not equal to score B (unless some coincidence in numbers). A better system would be to prorate time and speed with the square root of wingloading - time should be multiplied by this factor, speed should be divided by it. Then scoreB = 100*tB*sqrt(N)/tmax + 100*vB/sqrt(N)/vmax = 100*tA/tmax + 100*vA/vmax = scoreA Surface area can be measured by having the jumper lie on a big sheet of paper, making a cutout of his projection and weighing it. Or maybe you can take a picture of jumper against some odd color background and have the computer count the number of background pixels. Producing non-nonsense takes some effort, yeah.

Nidez 0 #3 July 23, 2007 Sorry Yuri, but this is not simple. do u remember the "Keep it simple" rule ? point 1 - we're going to measure the 3D speed with a minimum GR of 1 (45 degree) not the Vertical Speed. point 2 - i don't think the pilot of a race car is the 100% of the result... the car and the engine is important too. So if my suit is bigger than yours and i win also if you are a better pilot than me... buy a better suit ! that's all ! I asked Help in planning and ruling the competition a lot of moths ago, some of you guys helped me a lot, others show me that was not a good thing to have only a "national competition" so i managed to open it to the foreings too. now this is a partecipation call, Who wanna come ?Marco "Pazzo" Pistolesi pistolesi.marco(at)gmail.com Quote Share this post Link to post Share on other sites
yuri_base 1 #4 July 24, 2007 Here's an example. Suppose you only have 2 jumpers, A and B. A's time is 90s in the first round, speed is 100mph in the second, and glide ratio is 2.5 in the third. B's time is 75s, speed 120mph, glide 2.5. Their scores will be: A: (90/90 + 100/120 + 2.5/2.5)*100 = 283.3 B: (75/90 + 120/120 + 2.5/2.5)*100 = 283.3 They fly equally efficiently, and the 1.2x difference in their speeds and times is caused by difference in their exit weights: A is 170lbs, B is 245, same size, same suit (sqrt(245/170) = 1.2). So they split the grand prize in half: half the ticket to Stupino, half the helmet, half Paralog, one glove to each, etc. and all is well. Now, add jumper C (exit weight 138lbs, same size, same suit): 100s, 90mph, 2.5. Although nothing has changed in A's and B's flight parameters, their scores suddenly became unequal: A: (90/100 + 100/120 + 2.5/2.5)*100 = 273.3 B: (75/100 + 120/120 + 2.5/2.5)*100 = 275 C: (100/100 + 90/120 + 2.5/2.5)*100 = 275 How fair is that? A will be pissed, understandably. And C, aerodynamically, is not any better than A, he's just lighter, that's all. If, however, the speeds and times are prorated with the square root of wingloading, A and B still have equal scores whether there's C or not: without C: A: (90*1/90 + 100/1/120 + 2.5/2.5)*100 = 283.3 B: (75*1.2/90 + 120/1.2/120 + 2.5/2.5)*100 = 283.3 with C: A: (90*1/100 + 100/1/120 + 2.5/2.5)*100 = 273.3 B: (75*1.2/100 + 120/1.2/120 + 2.5/2.5)*100 = 273.3 C: (100*0.9/100 + 90/0.9/120 + 2.5/2.5)*100 = 273.3 So they each take home a 17% discount on an overpriced suit. That's fair. See, aerodynamics does matter!

Nidez 0 #5 July 24, 2007 ok, try to consider for just one second, what about if jumper A B and C have a Phacro, V-2 and Blade ? it's not same suit and wing surface ! how can you calculate the wing load ? Do you already have a program to do it and to be 100% sure of the result ? No ? ok so this is just a theorical math discussion and i don't care about it, mine is a parteciapation call. Yes ? Please give it to me and i'll use your way of evalutating differences between birds and suits. p.s. and why don't calculate also the difference of lift generated by the 3 different 3D design of the Wings ? there will not be 2 birds on the same 1st step of the podium, there will be a 1vs1 competition, something like "hop - fly a bit - and pop" where you jump from 2500 m and fly until 1000 with a smoke can, who simply fly more far wins, and the winner is selected by the whole competitors on the ground.Marco "Pazzo" Pistolesi pistolesi.marco(at)gmail.com Quote Share this post Link to post Share on other sites
Nidez 0 #6 July 24, 2007 Quote A: (90/100 + 100/120 + 2.5/2.5)*100 = 273.3 B: (75/100 + 120/120 + 2.5/2.5)*100 = 275 C: (100/100 + 90/120 + 2.5/2.5)*100 = 275 How fair is that? A will be pissed, understandably. And C, aerodynamically, is not any better than A, he's just lighter, that's all. Ok so let's cut away the problem, dont consider the speed competition, we have 1st place C with 200 points (100 sec - GR 2.5) 2nd place A with 190 points (90 sec - GR 2.5) 3rd place B with 175 points (75 sec - GR 2.5) consider the exit weight: C: 138lbs, A: 170lbs, B: 245lbs, same podium uh ? so my WRONG system of adding the spped competition just give some chanche to win also to people who are heavier ! this is not a "who's the slimmer" competition or simply Loic will win everything ! (he will win everything in any way ! ) p.s. my Wrong system also keep the suspance high, if A n B are on the same 1st step of the podium and after the C run they are 2nd and 3rd they can do another jump and put the whole high score in the washing machine ! this is not only a "take place" score, when you take the 1st place in a discipline you do a mess in the whole high score ! Suspance thanks !Marco "Pazzo" Pistolesi pistolesi.marco(at)gmail.com Quote Share this post Link to post Share on other sites
