Chris: I'm sorry but I don't really understand the problem or the reason for the answer unless it would be a lunch-height contest. Even then the question is "why?" I saw a fellow that could drive a golf ball further than anyone else, a world champion, but he never won a major tournament. I would like to study Joe Wurtz's video about finding thermals because I believe that is where the real difference between glider pilots is. Except of de-bunking astronomical launch heights, I feel there is little need to know how high the launch height really is. You bring one or two gliders to the park. You toss them into the air as best you can. If you wish, you measure the time the plane is airborn or better yet, hand catch it a few feet off the ground. That is all there is to it. As you know, I use a mini-hi-start (25 feet small rubber and 100 feet of thin line) and normally I get full extension of the line plus the plane will lift most of the rubber so I estimate the height to be about 115 to 120 feet. From there I try to catch a thermal. Without a hi-start, I toss the glider as high as I can. From there I try to catch a thermal. I'm not as acute about finding thermals as you and many others are so my plane often comes down rapidly reguardless of how high it got during the launch. The important thing with throwing a HLG is to not hurt yourself. Use the proper technique to not get a rotator-cup shoulder problem and then try to catch a thermal.
