Earlier this evening, I posted an answer to the query Coloring in Table of contents.
Since I was already at the daily limit for rep points prior to posting this answer, the first 3 upvotes didn't increase my rep total. Nothing unexpected so far. But then something novel and quite unexpected happened: The fourth upvote yielded two [2!] more rep points:
As far as I can tell, this is the very first time that I've received 2 points for an upvoted answer, instead of the customary 10 points. (Of course, one doesn't get 10 points after the daily rep point limit is reached.)
Question: Is my receiving these 2 rep points due to (a) some new site-wide policy regarding rep points, (b) some site-specific software glitch, or (c) some other reason?
Two additional pieces of information: (a) No downvotes, and hence no un-downvotes, today -- or, for that matter, in at least a month. (b) The answer that generated 2 rep points upon the fourth upvote received no rep points upon a subsequent firth upvote.
+245
-- down 2 points from the+247
tally shown in the screenshot. I have received no notification either as to why I received +2 for my answer to "Coloring in Table of contents" or as to why the 2 points were reversed subsequently. For now, I'm inclined to think that the answer to my question is simply "(b) some site-specific software glitch".
