Anyone with The Archery Program? TFOX?
Bonus if your bored 
I think TAP lets you do what I want. I would like to estimate the fps of the Hoyt Razortec C.5 and the Darton Magnum Extreme with CPS, with the following set-ups:
Draw weight- 80#s
Draw length- 28"
Arrow weight- 500 grains
Does the program let you calculate this? If so, would you. Thanks in advance.

RE: Anyone with The Archery Program? TFOX?
mshane, both those bows have stated IBO speed close to the 70# hornet I' m currently shooting. Out of my bow, I get 252 fps with the 500 grain arrow.
Sure doesn' t seem right... Did you plug in 80# draw weight?
Thanks for taking the time to do this

Yep I did, rechecked and came up with 252 for the C5, don' t know if i' m doing something wrong or what? Ah well....
If i use the same Bow Performance Factor that I come up with when I enter in your numbers on the Hornet, I come up with 273fps. That sound more like it...

RE: Anyone with The Archery Program? TFOX?
I was just looking at TAP web page, I don' t know what version of the program you have, but they have an update that is supposed to do a much better job estimating speeds with heavier arrows. Apparently this was a problem, and perhaps it is to blame for your findings...
Sure seems like it should be much faster...

I had a brain fart just a sec....I' m getting around 250 for the C5 and 252 for the CPS with TAP. Seems low doesn' t it?
Out of my bow, I get 252 fps with the 500 grain arrow.

RE: Anyone with The Archery Program? TFOX?
Silent, at the time that fps was chronied, 1 Tru speednok, nothing else. Since the hornet design is so quiet anyway, I prefer to have as much energy as possible transfered to the arrow. When I checked it at 29" draw, I only gained 6 fps with the 500 grain arrow. It' s a sweet, efficient little bow. It will spit a 350 grain arrow at 295, 28" draw at 70#s.
Mshane, I didn' t see your edited post with the 273 #. That is what I was suspecting.
How does the BPF work? Are the guestimates based on what my bow does, or what the other two should do given their design?

RE: Anyone with The Archery Program? TFOX?
The BPF is a hard number that TAP calculates by using FPS, Arrow Weight, Draw Weight, Brace Height, and Draw Length. I don' t have a clue how it extrapolates the BPF with those numbers. The 273 number was reached by putting your hard numbers in TAP and using the info provided by TAP for your diamond. If the IBOs are similar then my assumption is that their BPFs are similar. Hope this helps.....
