I did some research on how reputation is calculated. I am aware that when an action that effects reputation is taken, the denormalized integer that represents reputation, stored in the users table, is incremented or decremented accordingly.
What I would like to know is how this is done:
Is it per vote? So that the net effect of one vote is added or subtracted form the reputation score.
Is it per post? So that the votes on a post a re-tallied, and the value of reputation accrued on the affected post is applied to the denormalized reputation column?
