I know that you give back 15 rep if an answer is unaccepted:
Do you lose the 15 pts if someone later unaccepts your answer?
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.
