In my view gaining reputation on MSE shows much resemblance with fishing. Sometimes they bite, sometimes they don't. Often I wonder things like "why?", or "why not?".
Yesterday (11-11) I had my greatest catch ever, comparable with a $1$ meter pike :-). And this simply because I was the first, of course.
But what I noticed was that not all upvotes where accompanied by a $10$ points raise of reputation. In numbers: $15$ of the $31$ upvotes remained unrewarded.
I can imagine that there is a reason for that. Probably some "catch quotum" I thought. But when today I received upvotes again plus the usual raising I started to doubt my theory of quotum.
So my question is:
Was it according to some rule that the gaining stopped or did just something go wrong?
