I think there are 2 causes:
1. BPIP doesn't update all profiles at the same time, so theymos' DT1-update doesn't instantly reflect in the correct new order.
2. Some people have quite a lot of inclusions, including self-scratching. So their own Trust score changes significantly depending on whether or not they're on DT1.
Scrolling through
Most Trusted Profiles, there are many users with the same Trust score as yours. A small change is enough to bump you up or down quite a lot.
Sorry for the delayed reply. I was not aware how many users have same Trust score... wow!
Howeever, I don't think that was the reason for the change... I will explain:
- last time I posted here it was just after the DT change, when I was dropped to DT2. At that moment, my position on those ladders registered a fluctuation of 100 places (similar to current one)
- since then, my position on those two ladders faced only minor changes
- immediately after lattest DT change, when I returned to DT1, I noticed same huge fluctuation. So I believe that, when I checked my profile on bpip, the DT change was processed already.
Having these said, I think it would be a very big coincidence to have these huge fluctuations twice already, first time after being dropped from DT1 and second one after returning to DT1... So i believe this is the cause - the change from DT1 to DT2 and from DT2 to DT1. I will still keep observing this at each DT change I'll meet, but who knows when I'll go again to DT2... In any case, I will pay attention each month, after DT users are reshuffled and, when I'll go to DT2 I'll come back to confirm if same huge fluctuation occurred. My curiosity was if such a big fluctuation is normal...
