It really depends on who you ask, how it was tested, etc. A friend of mine once got 232 fps out of a longbow--with super light arrows, drawn to 29", and an excellent release.
There's gobs of ways of fudging the numbers, and people will do that for the simple sake of "bragging rights" to the "fastest". Chrony's are about as reliable as scales too--if they haven't been professionally checked and calibrated, the reading is questionable.
Nock fit, arrow spine, string construction, serving length, silencers, release (fingers, release aid, Hooter Shooter), draw length, arrow weight, tuning, brace height (drop the brace to 5" and shoot with a Hooter Shooter--you'll get impressive speed, but nobody would ever get real world speeds to compare), etc. etc. etc. all come into play. You can get speeds from a "test" that nobody will ever get close to in the real world, if you want to play that game. You can set one bow up to be the fastest, then you can set it up differently and make it a lot slower than another.
Seems that someone put up a pretty good reward a while back, if anyone could provide solid proof of a bow shooting at least 200 fps, pulled to 28", with 10 gpp arrow weight. I'm pretty sure nobody ever collected on that reward.
I've seen/heard gobs of claims, but haven't seen 200 fps @ 28"/10 gpp yet, and I haven't even heard it from a source that I know is credible.
