This is my table for a 313 fps arrow assuming a perfect parabola and an arrow that doesn't slow down. This shows an arrow zeroed at 25 about 5 inches high at 20 yards and 6 inches low at 30 yards. [Maybe a person could do better with some kind of planing? of the arrow. ]

At any rate, even with this very fast arrow, range estimation is critical even with fairly close targets.

But I think that Arthur P is right on! heavy has a lot of advantages. Speed just has this one (or two, I suppose, less time to jump the string). And penetration is generally much better with heavy, all else being equal.
