Hypotetically speaking -- If a member's most recent rated round for an update occurred on the 24th of a month, do 12 months worth of rounds going back to the 25th day of that month on the prior year get included or does the calculation include rounds going all the way back to to the 1st day of the month a year earlier?
also, have you considered putting a decription on the ratings page which describes the formula or do you like getting asked the same questions over and over?
