=Reference=
 * General
 * The counters are reset when the Digimon evolves. So, for example, nothing that happens to the newly hatched Digimon affects growth at all.
 * The requirements for Perfect Digimon are unknown at this time. Some battles are necessary.
 * Calls/Care Mistakes
 * When its hunger hearts run out, the call icon lights up. If you don't feed it for 20 minutes, it goes out again, and that's a care mistake. The same for strength. However, if BOTH hunger and strength run out, it's still only one care mistake. And if you leave it for a few hours before feeding it, and it bleeps again a few times, then even then it's only one care mistake.
 * Lights calls are straightforward - leaving the lights on for 20 minutes after it falls asleep is a care mistake.
 * Accumulating up to 4 piles of poop has no effect at all. (Larger quantities are unknown.)
 * Training
 * Only successful training is counted for evolution.
 * Overfeeding
 * 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.
 * Sleep Disturbances
 * 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 wakeup, then set the clock to some time during the day. The Digimon will wake up, with no effect on the counters.
