an actual draw force curve

(1/4) > >>

simk:
I rarely do this, as to me they all look similar. But in this one I was interested somehow. This is another Horn Wood Bamboo Composite. 65" longbow. minimal deflex. 4" net reflex. Stiff but light outers, basically a lever type principle. Cannot test fps because my chrono is broken. 195-200 @ 8 gpp is only my guess. And my sheet does not calculate the "energy storage factor" like virtual bow does. So I asked gemini AI to calculate and it said it was 120% which I do not believe myself  :) but its an intersting curve.

Badger:
 I see 99.9 % not 120%. It is 120% of the line below your force draw, what does that represent?

Selfbowman:
Looks like a great force draw to me.

superdav95:
Nice curves on the bow.  Draw curve looks smooth

simk:
Badger, I have not written that excel sheet and only understand Kinetic Energy and Dynamic Efficiency here. But the 99.9 you see must something different than "energy storage factor". This Energy storage factor to my undertstanding is the comparison to a linear straight longbow curve. In this case it must be above 100% because the curve has that hump and no stacking.

but this this is now leading me to the following question....

Please:

How do we draw the curve of that hypothetic linear comparison bow? It ends at 50@28. But where do we start it? What is the drawweight at 10" of draw? Why?
