I think it’s a pretty small demographic that post here to say what the Apple algorithm is doing. My mistake is completing every challenge since I got an AW back in October 2020. So not surprised they are getting progressively harder.
Well, in my experience, the good thing (if there is one) is that if I miss a really big one, the next month seems more easily achievable. Eventually it backs down and doesn't try to kill me. Last months was hard for what I was going through at the time, so this month is way more attainable. Coincidence?
I think it was two years ago: I missed three months in a row, and the next was almost as easy as falling out of bed. I had it by the beginning of the second week.
I haven't decided if the ring goals are to coach me, punish me, or inspire me. It does seem that the more I achieve, the more painful the goals get. It doesn't seem to take into account my age or the weather, etc. One month was 'Run x number of minutes this month', when I have near absolute zero running intervals ever in Apple Health, or Strava.
Punishment, harassment, or just clueless.
