I have a feeling the bows that shot the hardest were preferred,, they were probably pretty picky about their personal weapon if there life depended on it,, if shooting all year round,, I have a feeling they could tell which bows were best without a chrono,,, depending on availability of course,, the guys that shot the best and brought home the most meat,,,probably preferred the best bow they could get,,, in a pinch ,, hunting skill would have to make up for lack of cast,, I have a feeling the archers were more sophisticated than some would imagine,, just my thought
I am sure they shot bows for distance,, and a certain amount of pride or prestige would come from a hard shooting bow,, I dont think our mind set has changed much since then about that,,,,,
