After spending hours of time behind arrow trajectory software plotting out what I have journaled during yardage practice for 3D, as well as shooting the same bows setup for IBO at 315ish fps and then backing them down for ASA at 280ish fps, I can say that graph isVERY inaccurate.

The differencebetween a 275fps arrow and a 315fps arrow is less than an inch at 40 yards. This is such a small amount, that 99.999999999% of archersdo not shoot well enough to take advantage of this difference at all. There are also many other factors that contribute to the trajectoryas well such as shaft diameter, fletching size and type, FOC, etc.........

With that said, there will certainly be differences between shooting 275fps and 350+, but still most hunters aren't shooting out past 30 yards anyhow at live game, and those that are shooting out past those distances are hopefully smart enough to be using a range finder every time at those distances. If you don't have time for it, should you really be shooting at that animal?
