I always like to read these type of threads because of the many opinions expressed, with most taking a position their way is the only right way. So lets put this question in its proper perspective with simple math. The formula to find time is T=D/R with D being distance, and R being the rate or speed so here goes. I chose 15 yds.(45 feet) as distance to target, 3 rates of 190fps,175fps,160fps as the speed.
T= 45/190=.23684 seconds(A)
T=45/175=.25714 seconds(B)
T=45/160=.28125 seconds (C)
So: A-B=.0203 or 20/1000 seconds sooner to target
B-C=.02411 or 24/1000 sec. to target
A-C=.04441 or 44/1000sec. to target
So it takes arrow C approx less than a half of a second longer to get to target, show me a way to relate to that in real time. Facts are indeed facts and things that can be put into the truth!
