Trust me. A hunting setup will not even come remotely close to IBO speeds, and this means with any bow. For one thing very few people shoot a 30" draw and most people do not hunt with an arrow rated at 5 gr/lb. Also nobody hunts with absolutely nothing on the string. And most people don't know how to supertune a bow to get the most out of it.
My years of experience has proven to me that most hunting rigs will produce at least 50 fps less than IBO and an exceptional setup might get as close as 30 fps less. Most of this starts out depending on the draw length.
