So then I tried GT 22's at 366 gr now im getting 305 fps. with a 30" draw 68.8 lb and all the arrows cut to 29". So I don’t know if the site you are referencing is not being bias toward Mathews.
Im not saying that i have one of those speed bows but i do think that if you play with arrow weights youcan get the speed or close to the speed that they say. JMO
Yep they did and got them cooking. It was a bunch of you tube vids done by some guys in a shop can't remember which one.
294 is a far cry from 330+. I've gotten 291 out of my 2005 Hoyt protect with close to a 400grn arrow. Gotten it out of my brothers 2006 as well. I'm just thinking they should at least be over 300. The Mathews was.the only one. Didn't do the math but what percentage drop is 366 to 280? Seems sixable and at least worth a raised eyebrow.
I'm not up on bow dynamics but if it's like others thing it's possible the word "develops" is implied. Add a load and things change on a large scale. Electric motors are like that. Size really does matter in a motor. Doesn't take much hp rating to start getting a large motor. 3hp is pretty large unless you get one that develops it. It might develop 3 but it won't have the guts when you hit it with any kind of a load.
It's all energy. I also don't know in what way they were impeding/friction on the arrow. Things might not even have been setup right.
