As a general take-away, if you were to do-your-own "Chung-ing", what would you look to test/iterate through? I'm also wondering how well a 2 state (high/low) multifactorial design of experiments would tease out maxima/minima given the nonlinear interactions between different setups (e.g. a helmet may do terrible with flat forearms, but then becomes the best when you mantis).
That said, the more variables I can eliminate, the smaller the test table gets. As it stands below, it'd be HUGE to test every combination. Obviously I'm $$ limited on what goodies I can test as well, albeit with a lot of tri-friends, I can probably muster a lot of equipment. :) When I find myself doing fits, I usually trend towards Andy Coggan's "caveman" fit suggestions. Looking to get smarter than that.
* Hands/elbows
1.) Higher/lower
2.) Further/nearer
3.) Flat vs uptilt forearms
4.) Narrow elbows vs wide
* Helmets
* BTA setup vs nothing vs ?
* Clothing
Am I missing any variables? Any that I can safely "assume" are linear in their interaction with the system?
Jim can probably give you a bit better answer than me. But get the position first then find the helmet. In other words, if the Mantis is the best with the baseline helmet, test other helmets to see if it works. The mantis is one of those that doesn't work on a lot of people, but when it does, it works very very well.
Hands level or just above the elbows.
Position, helmets, clothes. At some point you just have to decide what to test. I didn't get to test everything I wanted because I ran out of time. I think a lot of us were like that. If you are field testing maybe set aside one day for each thing. Day 1 Positions, 2 Helmet, 3 clothes. That what I would do FWIW.
