I apologize for contributing to the hijacking of this thread! But i just had to weigh in....

I have to agree Danny.....Unless you got THE fastest Deviator in the history of mankind something is screwy with those numbers.

Hoyt lists the Deviator at your specs (70#/30" ) at 9grs/lb. at 239-245fps. ( THAT' s with a 630gr arrow).........which equals 80-84ft lbs of KE. Nothing to sneeze at for sure, but that' s at 70# not 67# and with an arrow 100grs HEAVIER than yours.
WIth a 520gr arrow and your specs of 30" /67# you should be looking at something like 78 ft lbs of KE ,and that' s top end. Again nothing to sneeze at, but a far cry from 94ft lbs of KE!

Look at it this way........to get that number you quoted you are looking at a bow that would need an IB0 rating of about 352fps!!!! (I don' t think there is a Hoyt rep alive who would tell you a Deviator at 30" /70# could shoot over 350fps.

If I had to guess, you actually DID see a 285 from that bow at 67#/30" but there is almost ZERO possiblity that that arrow could weigh 520grs.

Heck my Pro38 Dual Cam BowTech had an IBO speed rating of 333-340 and I had it going 336fps with a loop only (339-340 bare string) This bow with a 474gr arrow would only do 290fps and that' s a full 46grs lighter than your arrow, AND I was shooting 30" /70#!

Granted the Deviator was a beast of a bow........but lets not get carried away!
