Look at my reputation today (+231):
I got two accept ticks, which award me 30 reps in total. Therefore, I got 231 − 30 = 201 reps for votes received.
I don't get any reputation from the upvote on top, that means I hit my rep cap today, i.e. I can only gain reputation by acceptance or bounties, etc.
Therefore I see that I hit the rep cap at 201 rep, not 200 rep.
Take note of the 21 rep I received for Improve appearance of matrices as arrow labels in tikz-cd. I think it should be 20 rep.
Quite surprisingly, /reputation is correct:
