Thanks to drunk for send me this link:
http://www.paralog.net/...hp?equipment=Ghost+3

But i don't understand
http://www.paralog.net/...p;trackid%5B%5D=1201
How the same jumper with same Ws , the same day (only 3 hours between tries) could score:
903m at 151.4km/h AND 1909m at 248.4km/h
(same 1000m vertical)


When i see the score of the V4 video :
http://www.paralog.net/...hp?trackid%5B%5D=905
Is it possible without 40 kts downwind? Crazy

This data looks more like a tracking suit jump than a WS jump...

When looking at any of these figures you should bear in mind that they can be greatly affected by wind, diving/flaring & for base jumps thermals.

The two tracks you posted are in opposite directions (but as drunk pointed out second one looks like profile of tracking jump). It's quite possible that one is down wind and the other upwind. The winds aloft could also have changed in the 3 hours between jumps.

Of course it's possible there was a strong tailwind on the jump in the video, but I'd guess less than 20knts. I suspect there is a strong tailwind on most skydives showing a sustained GR above 2.8:1

For every 10knots of tailwind you can add about 5meters in distance per second of flight. In the Paralog competition the vertical 1000m usually takes 50-90 seconds. 40 knot tailwind for 60 seconds of flight will give you 1.2km extra distance!

Got a high tail wind, fall slow. Got a high head wind, fly fast.

Whatever tail or head wind, time is independant.

When i read 30s at 150km/h, jump after 60s at 240 CrazyCrazyCrazy

This data compilation is nonsense if isn't notify type of fly tried ?

Everybody agreed there is 40kts tail wind in the video above (V4) ???

I hope not average glide for the jump (exit to open) was 2.2

That was my videoed V4 performance run. I had a tail wind of 18kts at altitude on that run. I determined the wind from the difference b/t indicated airspeed from the plane and GPS ground speed soon before I left the aircraft. Once I left the aircraft I had a really fun time :)

18kts, that's mean GR=2.55 and 181 km/h during 50.6s
Angle= 21.4 : true speed=194.4 km/h


105kts and -4176 ft/min Not so far of a plane !
