The reputation cap is supposed to be 200? I'm at 533 on the second day. That shouldn't be possible? Am I misunderstanding how reputation caps work?
Remember that reputation cap only affects upvotes, not acceptance bonuses.
It's actually perfectly your highest possible reputation. You started at 101 reputation. Then, for 2 days, you earned 400 reputation putting you at 501. Then, you have two answers accepted (+30), and accepted one answer (+2), ending at a nice 533. Well, 532 if you include the one downvote you've cast.
As a test, I gave you an upvote on a post of yours. Your reputation still looks like 533, and I don't think it's going to change.
Reputation gained from accepted answers and bounties is immune from the cap. If you check your reputation report (https://gaming.stackexchange.com/reputation) you should see 200 coming from votes and the rest from acceptances.
