boo backed bamboo bow

I narrowed up my tips to 3/8".   The forcedraw curve shown is out to 25" draw at 58.80lbs.  brace height from the back of the bow to the string is 6.5".   I measured the first 1/2" to 7" then every inch after that.   The question is do I keep going?  or do i call it where it is as i will not likely reach my target of 70lbs at 28".  It might be close.  if i go to 28" i figure around 65-67lbs???  let me know what you think.  the set back is holding pretty well so far.  only lost about a 1/4" right after unstringing. I suspect it will creep back most of the 1/4" through the day.  what think you fellers?

This is looking super snappy, I really like the profile it's keeping! Are you going to wait until the salt flats to do any full draw or shooting with it? It's looking awesome so far.

Thanks Robert!  It feels snappy.  I’m gonna take this one as well as a few others out to a long field to distance check in the spring.  I’m Just putting the finishing touches on my flight arrows so will have something to shoot.  I’m also trying to decide whether or not I should continue with this bow or not as it will come short of my 70lb target.  More like 65-67ish.  Looking for input from other bow nerds to take a look at the draw curve and give me some direction on this one.  Not really sure what to do with it.  Option 1.  Reduce it down some to 50lbs at 26” like my self bow or option 2. Try to continue out to 29” draw and hope I’m close enough to 70lbs.  Option 3. Start over.   For all those reading and following should I try to take it to 29” and hope I don’t be way under 70lbs thus having to shoot a longer arrow also but it may be worth doing still???  Let me know what you think.

I've recently read something interesting, I don't know if it's relevant here and it sounds relatively risky anyhow:

Some flight archers shooting to break records will intentionally overdraw a lighter bow, say a 45# @ 28" drawn to 50# @ 30" (hypothetical numbers). Rather than shoot a bow that has been tillered to 50# @ 30# off the bat. I wish i could remember where i read this. It seems like a way to under build a bow on target for very dangerously low mass intentionally and squeeze the very most out of a flight bow. Maybe it also ensures compressive stress is kept to an absolute minimum prior to shooting.

Does this ring true or make sense?
