During experiments of this stuff at a big company (which saw a large portion of the web during this time):
- we saw most (>80%) of users staying on a web app ~2-3 days (most likely skewed from people leaving tabs open over the weekend).
- 95% was ~2 weeks
- 100% was about 600 day (yes, apparently we had users with a tab open for nearly 2 years)
If you are seeking 100%, you are going to be waiting a while.
: this is 100% from memory, I don't work there anymore.
I'm impressed you kept the measurements going long enough to track the 600-day users though!
