 Re: [base754] Prodigy
I am currently working on finding the sweat spot for max glide ratio

To find the sweat spot you must wear an all black suit on a very hot and humid day. Walk around on the tarmac for at least 20 minutes before the plane arrives. Before long, you will be sweating profusely.

Seriously though, this is going to be entirely dependent on weight and body type, and with all the variables the problem is still way too complex to get any reliable answer here. If you can really control your fallrate that precisely, then here is a simple experiment you can perform to find the answer on your own:

Do a flight at exactly 40mph.
Do a flight at exactly 45mph.
Do a flight at exactly 50mph.
Do a flight at exactly 55mph.
Do a flight at exactly 60mph.
Etc.

Wear GPS on all flights and compare results. Go through your data and make a graph of your glide ratio vs your fallrate. When you're done with that, throw it away because it's meaningless. Just as there are too many variables to analyze, there are too many to control during the jump. Add to that the fact that I can fall 60mph STRAIGHT DOWN or I can fly very fast forward at 60mph fallrate, and you realize that there is no direct correlation between fallrate and glide ratio only. Whatever your max glide ratio is, you may be able to get it at 2 entirely different fallrates, and even everything in between with different body positions. With an airplane with only flaps for control it's a different picture... but we have too much surface area we are able to move.
