RE: for all the speed demons out there
This has been so beaten to death. They are getting those rating with an arrow that weighs about 3 grains per pound. The advertising is misleading and some people believe anything they read. If you are comparing any characteristic of a bow be it speed or otherwise then go shoot that bow and then do a hands comparison of it and other bows. Then after you do the comparison with identical arrows, chronos, accessories etc. then take that information as fact.
