job was to send out the coefficients each year to a user base of a couple of thousand. Not sure why, but more often than not, they would release them at the last possible minute
Sounds a lot like the major policies of a political party....
Election on the Saturday....no worries, we'll release everything for you to scrutinise all the details on late Thursday, or for the really sensitive ones early Friday morning.....just to give everyone plenty of time to distinguish between the parties platforms.
Limits the flak.
