I just read the whole thing too.
For what it's worth my thinking on recurves goes a little like this.
The whole point of recurving is to reduce string angle leading to more stored energy over a straight limb design.
More stored energy is good but can be lost to excess weight in the tips.
Recurving also increases strain over a straight limbed design.
Increased strain = crushed belly cells which in turn reduces the return speed of the limbs.
To lower overall strain but still keep the benefits of reduced string angle deflex the limbs near the handle and reflex the outer limbs to blend into the recurves.
I agree with Badger 100% the keys to fast bows are simple. Low string angle, low weight outer limbs and more important than anything - FRESH wood.
The fastest bows i've made are reflex/deflex recurves. The best shot 212 fps with a 8.9 grain/lb arrow and that was without an optimised string but the bow was still 'fresh'. It has since been shot a lot and now shoots 185fps @ 10gpp. It is an absolute dream with literally no handshock and so quiet for a recurve.
I have been planing on trying to really optimse that design but getting good enough staves is more than a mild problem...
and then there is the time needed.
