Twanger, in the last 5 years I have only shot hoyt and HCA. That means ten different models between the two brands. After I set them up for an IBO comparison(thats the first thing I do) I think that every one of them was within 5fps of advertised speed. Well, let me clarify, I shoot a 29" draw, so whatever speed I get, I add 10fps to the custom chrono reading for the 1" of draw I give up.
I know a bunch of guys that shoot mathews, and if they are slower than advertised, it is not by much.
Hey, this is what I have found in my setups, maybe not typical. I don`t put any extras on the string when testing for speed.
1. Tied in nock set.
2. Super peep/minus aperature.
3. One eliminator button for below nock.
4. Serious tune job before hitting the chrono.
Come to think of it...that`s all I put on my hunting bow setup, too!
