Let's suppose you exceed the reputation limit (you would have received 210 rep if the limit werent there) . Then, before the next day, someone downvotes one of your responses. Then your limits are:
BEFORE DOWNVOTE 200 (210 w/o limit) AFTER DOWNVOTE 198 (208 w/o limit)
Shouldn't the rep be boosted to 200?
(In my case, yesterday I hit 243 (where I should have hit 245 -- I see partial points for an upvote, which suggests there are some points beyond the limit)
