You certainly nailed the "bows with tips in the same position at rest should theoretically shoot the same".  Be interesting to see  if that's true.

  I would like to see  you just make  a same weight bow with short statics and not try to achieve the same tip position.    Have it match the reflexed curve plus have the tips a few  inches to the back.

Remember we have to test it first. I thought I might hear that from you right about now. You get me thru this without more than a 1/2” more set. Let me take it to the flats and shoot it it’s yours!

Sounds like fun. And some pretty good motivation to.

I like where you are going. I think it looks really nice. I see that same spot you mentioned. It’s really close though to my eye.

What weight you at 25”?

Your hooks are working about what?  3/8ths an inch?

Whats working length of limb?

Target is 50@28” correct

With those working hooks the profile a brace from
One did of that length end up looking like they bend more on outer third. I think its hard to have guys judge without seeing the pyramid profile. Looking at it in tree will fool folks thinking its a flatbow. The Super Pyramid is a different animal entirely. I had to shorten mine as i started seeing limb not returning to unbraced profile i wanted. Glad i did. Cuz i dropped some limb mass and in end got some more top end out of it.
I think at that length its a trade off how much tips cant take vs how much you have to thin limbs to get to tiller. I opted to have outer third bend more. Seemed to work?

If anyone can "build two bows just alike except". your the guy.

there's something to be said for your approach of settling on a good design and see how much you can fine tune it.

I posted this on another thread, but here's what I think might be a great profile... it's one of Marc's bows.
Seems like common sense isn't very common any more...

That one looks like a working recurve and I've never had much luck with those.  Profile looks good except it could work a little bit just before the recurves

Marc thanks I was thinking the same but it’s scary thin there. I took some out at the fades and rounded The handle a bit in that area.pic coming. Had to add to the side of handle because lack of stave. Growth rings where to good not to give this stave my best go. Listing close here guys thanks Arvin

Yes, two sensor Chrono’s are notorious for giving slightly higher than actual speeds based off a good three sensor or doppler.  As a rule i subtract 15fps off any two sensor Chrono.
