First we find out why, and the structure makes that answerable: if every video on one angle failed, the angle is wrong; if one creator's videos failed across angles, the match is wrong; if hooks died in the first second, the openers are wrong.
The next batch then corrects the specific failure rather than reshuffling everything. That is the practical difference between buying videos and running a creative system: underperformance becomes information instead of a refund argument.
