Is there an official calculation for the trust score?
I asked this question once, the answer I got was: You get +1 every month for every trusted feedback.
When looking at my trust, that cannot be true. I got a feedback on the 20th of November 2015, today is the 26th of January 2016 and my score is still 2.
While other users get +1 score only days after they received the feedback.
That is quite vague, theymos hasn't specified it. Most likely any answer about it , except from mods/admins will be speculation. Some speculations I have are
1) Your rating increases faster on the first month
2) The ratings are increased on one specific time , same as activity update
3) There are date limits on when the trust rating increases, i.e say if you get a feedback on 5th and the "limits" are 0 and 15 , the date closest to the date the feedback was received would increase the rating by one. Another example is if you get a feedback on 10, you will gain a rating increase on 15th.
I've heard something about the risked amount having a big role in the calculation too. Not sure though.
May anyone help me?
That was changed, amount AFAIK doesn't affect rating anymore
