Obfuscation at its finest.
I don't think anyone is saying thatbowhunters should
depend on compensating for a poor shot except you

.
I wish there were no poor shots too but animals move, winds blow, twigs/branches go unseen. Apparently there is something wrong with telling folks things don't always go like we plan and that being prepared for less than ideal results is wrong.
Luck is when preparation meets opportunity.
