I was reading the article titled, "The Fine Art of Swoop Survival" in June's parachutist, and I came across a paragraph that raised some questions? I'm sure 99% percent of you have read that article so i'm not going to rewrite it verbatim. They wrote about practicing front riser turns and counting the seconds until the building pressure on the front riser, forces you to let up on the riser. Then they gave an example of 4 seconds. In the next paragraph they say that a 4 second 90 degree turn, will lose as much altitude as a 4 second 180, 270, 360, etc. Is this true? I'm not saying it isn't, but can someone explain to me how that works. It seems to me if you are making a 360 in 4 seconds the canopy will be in much more of a dive for those 4 seconds than on a 4 sec. 90 or a 180. Also, if the 4 sec. is based upon the time it takes for the riser pressure to become too great, how do you make a 90 last 4 seconds and build up that same amount of riser pressure, without over turning? I'm a beginner in the sport so I'm not familiar with any of this. I won't be able to jump for about another 2 months, so I can't go out and try it this weekend. This is probably a "try it and you'll see" situation, but if anyone can explain more in depth how it works, I'd appreciate it. Thanks.
