The best solution for IBO speed checks, IMO, would be for an independent agency to test the bows instead of each individual company doing their own. Weigh every bow, measure every draw length, use the very same arrow. In other words, set a common standard for all bows.
Now let's fast foreward to the real world. Very very few people shoot a 30" draw unless they are drawing a couple inches too long. The vast majority should be shooting closer to 28". This means about 20-25 fps less speed right there.
