Hmmm, interesting discussion. [&:]

K N, I believe the scenario quoted above is entirely possible, & many times be mistakenly attributed to superior 'cast' of one bow over another. If the test arrow were spined properly for bow 'A' & not for bow 'B', then a cleaner launch & less in flight gyration would certainly allow the arrow from bow 'A' to travel further than from bow 'B', even tho both bows released the arrow at the exact same speed. To the casual onlooker, bow 'A' would appear to have better cast.
