Injuries occur a set amount of the time when certain on field events occur. There is no “this guy is going to get hurt today because we need to allocate injuries” function. If you have 15 levels of minors vs 2 you should see the same amount of injuries at the highest level more or less. I say “more or less” because players on reserve rosters never get hurt except by the random, rare, and usually very minor off field injuries (which are mostly things like the flu) and you might be accidentally doing something with your own minors that increases injury risk, like not carrying backups at some positions or having a bullpen situated so more guys pitch while fatigued (fatigue is a really high indicator of injury chance, perhaps as much as a player’s individual injury rating itself).

Otherwise the one tweak I think I’ve seen is that for long running leagues sometimes the league as a whole gets way too injury prone and veterans especially can’t stay on the field. I don’t think this has ever been really properly tested because it requires too many moving parts (you’d have to sim a league for 20+ seasons and then look at total injury time missed but only from seasons 21 onward, and then maybe further broken down by position and age. I’m not even sure where you’d get that first number except by scraping player history, and I think testers by and large focus on or at least include the early seasons because the vast majority of players don’t get that far into games, and recalc papers over a lot of these issues for historical leagues, which are the main places where people want to build up history before playing). Even here tbh I usually just try to work around that by manually editing down players’ injury ratings when I see them and when it’s not basically too late, but even this probably only really hampers the careers of a handful of players per 3 to 5 year period.
