Clearly the cycle doesn’t restart every time I wake up, if it ends at the ~1.5hr mark (which by the way is quite fluid, sometimes as little as 30min, sometimes it doesn’t happen until 9am).
I have tried figuring out both cycle length and falling asleep time, but thanks to my raging ADHD I sleep quite restless (it’s frequent I wake up 2-3 times during the night), and need lots of time to fall asleep (and no, melatonin sadly didn’t help). So for me this trick works.

Did you ever notice the time between wakings? For me it’s three hours pretty much on the dot — i.e. I have a regular 1½-hour cycle, but prefer sleeping for two cycles minimum for some reason, and do the same with naps.
As for the cycle being restarted, REM is deep sleep, so you’re unlikely to get it if you’re woken up all the time.
It’s quite random, the time between wakings. If I go by smartwatch data it’s anywhere between 10 minutes and 4 hours. Consciously remembered ones, those are almost always 2 hours on the dot.
