I know that you give back 15 rep if an answer is unaccepted:
However, does this loss happen on the day the answer is unaccepted, or does it apply retroactively to the day that the answer was accepted? Can you drop below 200 for a day in the past from this happening?
If the above is not true, can a reputation recalc still cause the unaccept to be applied retroactively (and a drop below 200), or does it remain on the specific day it happened?
I know that accepts (and unaccepts) won't accept the rep cap, but this could have implications for the number of days calculated for Epic and Legendary badges.
