The counters (except for battles) are reset when the Digimon evolves. So, for example, nothing that happens to the newly hatched Digimon affects growth at all.
Food and strength: When the Digimon's hunger hearts run out, the call icon lights up. If you don't feed it for 20 minutes, the call icon goes out again, and that's a care mistake. The same for strength. However, if BOTH hunger and strength run out, this counts as only one care mistake. And if you leave the Digimon for a few hours before feeding it, and it bleeps again a few times, then even this counts as only one care mistake.
Leaving the lights on for 20 minutes after the Digimon falls asleep counts as a care mistake. If the Digimon falls asleep with empty hunger or strength, this still counts as only one care mistake.
Accumulating up to 4 piles of poop has no effect at all. (Larger quantities are unknown.)
Version 1: A training session is counted whether or not you complete all 5 rounds. It's counted if you win, if you lose, or even if you cancel in the middle. (Where there's an upper limit on the training requirement, be careful of this.)
Versions 2-5: Only successful training is counted for evolution.
To overfeed, stuff the Digimon with food until it won't eat any more. It is necessary to wait until it loses a hunger heart before overfeeding it again.
Wake the Digimon up by going into the Food menu, training it, or selecting the Battle option.
If you want to wake it, without this being counted as a sleep disturbance, then set the clock to some time during the day. The Digimon will wake up, with no effect on the counters.
Perfect Level Requirements
Minimum requirement: 15+ battles at either Child or Adult stage.
For a good chance of evolution: 15+ battles at both Child stage and Adult stage.
A high win percentage improves the chances of evolution, but battling at both Child and Adult stages is more important.
