I dunno???
My BC says 70# 29inch 320fps. I got 321fps with a 349 grain arrows after I got home at those specs. Adding peep and kisser only dropped me 2fps to 318fps. After I chose my arrows set them up and adjusted draw weight to 5 gpp. Ended up at 310 grains at 62# pounds. It still yields that same 318 fps. Lost zero efficiency on my set up dropping from 5 gpp at 70# to 5 gpp at 62#.
If I run a calculation using a generous 92 grains of virtual mass you would need 90.4 ft lbs of stored energy to generate 318 ft/sec. Thats a stored energy to peak ration of 1.46. That's pretty hard to believe.
I checked Antler Eater's numbers for just the Allegiance and they seem reasonable. S.E.P. of 1.34.
