Is this some sort of new Mathematical approach for tillering and bow building. Calculating weight, draw length, 13:17 bend/lever ratio and limb length according to some past experiments. Is this better than tillering for Dummies. At the end of the day is the bow indestrucable built this way.

No, not indestructable in the least. As matter if fact, this builds it as close to the point of self destruction as possible, without crossing the line. High performance is on the edge of limits. This method takes you there but carefully monitored wood conditions so damage doesnt sneak up on you, you stare at it the entire time. Its an extreme sport building this way.

It's just a way of checking how you are doing for set. You go back and forth on the tree to try and catch any set as soon as it starts. Before you can actually see it. No math there. I'll go as far a grade school arithmetic but not math. My mind just glazes over when I see brackets and stuff. I still think the 13:17 is funny. It's so close to 3 to 4 but maybe the prime numbers made it look cool. Draw length according to working limb rather than total limb makes sense but I have to think about that some more. No rocket science, just shade tree engineering for those of us that just "have to know how things work". Does it make a better bow? Marginally. Won't kill a deer any deader. You might win more beer using these methods ;D

Sleek, I'll try and keep track as best as I can. I still haven't quite figured how I'm going to write this all down in an understandable way but we'll see. I'll be out there shortly.

OK I've got it all trimmed up and temp nocks on. One limb took the glued in reflex a tad better so I'll make it the bottom limb for now. I put it on the tiller with a long string that hangs about 7"and pulled it to 9". Got 36# exercised a 10" about 20 times, back to 9", got 36# again. 10" was actually 47# so I went too heavy. Pic is 9"
Bayou Ben:
Well you know you didn't hurt anything; the weight didn't drop at all.
11 lb gain from 9 to 10" (A). I guess you know you have good early draw weight.
