Does anybody believe the IBO speed ratings?

A buddy bought a bow that had an IBO of 308. When it was set up for his draw length - 26.5" with a peep, turned down to a little lighter draw weight and a 412 grain arrow, it only shot 220 fps. Still good enough to take a deer, but nothing like the advertised speeds.

The IBO ratings are fantesy. Don't judge one bow over another by a few fps. In real life most of us are lucky to get 75 - 85% of IBO.
