Way to often the chrono is used to just sell product and folks are given numbers that don't mean anything in the real world.
In the old days we would use the AMO standard to measure bow speed and that was as I remember 60# @ 28" with a 500 gr. arrow. That rating was what I considered a good test of a bows preformance for both trad. and wheel bows as it was close to what a normal person would shoot.
Then came along the IBO test and every wheel guy out there thinks their new latest/greatest shoots at 320+ speed, but no one read the fine print.
IBO standard is a 300 gr. arrow with no fletching, bow set a 70# at a 30" draw with nothing on the string.
I have never seen a hunting bow in the woods or a target bow for that matter, that looked like that, shoot by 6' 5" guys with 30" draw.
I would think one would expect to drop at least 20 to 30 fps off of the IBO rated speed when the average Joe/Jolen rigs out their hunting bow with string puffs, 55 to 60# average weight at 27 to 29 inch draw, etc. but the sad thing is alot of folks are dupped into thinking they have something they don't.
I really hate to see the traditional archery community go down the same path as the wheel guys have and a lot of us don't, as we know what really counts when it come to what make a great shooting bow. But we have a lot of new folks coming onboard that came from that speed world that think you have to shoot over 200 fps to have a good trad. bow and there are some bow builders that are taking advantage of that.
It's up to all of us who have been around stickbows for awhile to educate the newcomers to what it means to have a great shooting bow and how to use it so they won't become sucked down that speed hole again.
