What we have currently is this:
- Trust levels 2, 1, 0 cannot be lost automatically
- TL3 has a 14-day grace period, starting when you get it
- If you go below the “low-water mark”, demotion is instant (90% of promotion requirement / “high-water mark”)
Perhaps better would be a notice PM when someone is in the “middle zone”, between demotion and promotion marks? Under the requirements, but by less than 10%.
For a situation like this, a possibility would be to lock the user at TL3.
