BATTLESPERBOT setting

If I recall correctly, even if all bots have more than BATTLESPERBOT battles, bots with less battles get some priority. An other priority is 'old' battles (where f.e. the last battle is from 2020) even if those bots have a lot of battles. Also if I recall correctly, in melee there is some protection to prevent battles between only 'new' bots, I think only 1 new bot per battle and the rest quite randomly. Setting the BATTLESPERBOT higher does not influence this. Ofcourse bots with incomplete battles always get the highest priority.
