    I believe certain things like votes being removed are not shown. Not sure how time is involved? Commented Jul 23, 2014 at 13:20
  • @MatthewRead "Action removed" matches my suspection. But a diff of 15 rather suggests an "accept" retracted on the same day it was placed.

  • Exactly one user had accepted my answer but suddenly un-accepted it (don't why did he accept it then) but this un-accepting answer didn't reflect in the update

The difference in rep-points is 15, which suggests someone might have accepted one of your answers before you checked first time (46), and decided otherwise during the same day (46-15=31). As that makes 15-15 on the same day, it's not shown as one action canceled out the other "immediately".

  • Alternatively, it could be one person upvoting three of your questions, which was later detected by the system as serial upvoting and automatically reversed. I don't know if the serial upvoting detection runs that often, though.

  • Usually not, and whenever I had this, it was accounted for in the stats (being a different "user" taking the "reverse action" I suppose to be the reason there).

As for the extra 1 you haven't accounted for: every user starts with one reputation point, not zero.
