A bit of a late response, but check out a thread (
Target Minutes - An argument for trying them.) I started a while back. I'll bump it for you as well.
For future reference, a very effective way to choose target minutes is by using your exhibition games to experiment. Set the depth chart the way you want it, use fatigue settings to where you hope to get the guy (for you, sounds like
getting tired or even
tired is what you are going for), and see how many minutes he gets in each exhibition game.
1: in a slowdown zone, what sort of minutes could a 74 stamina play without getting exhausted, as a midway point.
Without getting exhausted, I think he could probably go near 30-32 minutes. If you don't mean exhausted, but some lesser fatigue level, I think around 22-24 at mostly fairly fresh.
2: if I give a starter low target minutes, is it really going to give the starter, say, 9 to 13 minutes?
Yes, provided you have sufficient minutes allocated to his backup(s) to fill out 40 minutes at that position.
3: if I don't put down a full games worth of minutes, what happens to the leftovers? What if you put down more than a full game's worth?
I tested this at one point, but honestly don't recall the results. I believe the starters are given the bulk of the remaining minutes if not enough are allocated. Similarly, I believe the starters are given priority, so if you allocate 300 minutes, the starters will be given the chance to reach theirs at the expense of backups. I think. I will test again in an exhibition and try to remember to report back the results.
4: what happens in overtime?
The same thing as regulation, I believe, in the case where you do not have sufficient minutes allocated. Starters get the most burn.
