Del the cat:
IMO the maths will tell you nothing.
Maths is a useful tool when applied to homogenous materials used in narrowly defined conditions.
Some rules of thumb and simplifed maths can provide some guidance, but I don't think it's much of a pedictor of anything unless your tillering is 100% consistent and I don't think many will claim taht with self bows.
I'm happy to be proven wrong, but IMO the time spent on maths would of ten be better spent running your fingers over the limbs.
My fave quote of 2016 was from Chris Boyton (a respected bowyer) I was discussing my Osage flight bow with him and saying I was wondering if I could maybe take some weight off the tips.
He said...
"You can always take more weight off tips"
The truth of this is obvious when I look over my bows, the tips get slimmer and slimmer as my experience increases.

BTW Handsome looking bows.

 Del, working on English longbows I can take about 15 seconds before I start and run some numbers and know exactly what the bow will look like when I am done. Based on weight and what job the bow will be doing I can use the math to select the best wood for the job. Even though the math is more of a rule of thumb and not an exact science I guarantee it will get you close enough for an excellent start. Some experience does come into play with knowing what to do with the numbers.

I once worked out the perfect taper rate for 72ntn elbs (from memory 0.009" taper), I generally used hickory back, boo cores (consistent weight and stiffness) and ipe bellies. I put all the taper into the cores, parallel back/belly lams and 12 - 16inch powerlam depending on weight. By adjusting the core thickness I could get within 5# desired weight most times and pretty much perfect tiller or very little work needed. It can be done by numbers but it didn't seem 'right' somehow ;)

10 bows in a few months is good going! I would say that the one with the least handshock and least set will be the best :)

Selfbowman:
Del I am not a math guy for sure . I do most by feel . I just thought the math wizards could give me a guess at my mass reduction and either tell me I was close or not to worry cause I was close enough. Just build the bows Arvin.  ;D I love the challenge in every one. I have been working on this real dense bow also 69" 42@26 may have to cut this one off.its quick though. 500 gr arrow 175yd.

Selfbowman:
Steve the mass may be in my handles. None are just alike but all very similar. All depends on the stave I make them a little thicker so I can cut my shelf in.
