    why does MATHEWS rate IBO as "up to 343"

    why does Mathews rate their IBO with " up to 343 fps"? other manufacturers simply just list the speed under IBO. Is there a difference ? is there some meaning to that or Mathews just wanted to give some variance to their IBO. meaning all bows may or may not hit that rating. idk I was just curious.

    I thought most did that. Or they list 343-347 etc....

      It’s perfect tune to a poor tune and a draw weight to draw length thing to avoid litigation,

        If you do some research you will see that there are "+/-'s" for the draw length and weight. Simply put they don't have to strap out at exactly 30" and 70#'s to be considered IBO test specs.

          As far as Mathews goes, I believe the “up to ###” comment is attributable to certain bows having more than one let-off module option. A lower let-off mod is going to be faster than a high let-off module (i.e. 75% vs. 85%).

            Same reason I write 'up to *** sq. Ft of blah blah" in my contracts .If I' m off by 2 sq. Ft. you're not getting a credit.
