During the Wheezy freeze, the Debian release team deployed 3254 hints. This number may include some duplicates (i.e. where two members of the team hinted the same package), it certainly does not include a lot of rejected requests <insert more disclaimers here>.
The top hinter was *drum roll*… Adam, who did 1799 hints(That is 55% of all hints during the freeze). For comparison, the second and third runner ups added together did 1023 hints (or 31.4%). Put in a different way, on average Julien Cristau and I would both add about 1.5 hints each day and Adam would on his own add 5.6 hints a day.
Of course, this is not intended to diminish the work other the rest of the team. Reviewing and unblocking packages is not all there is to a release. Particularly, a great thanks to Cyril Brulebois for his hard work on the Debian Installer (without which Debian Wheezy could not be released at all).
 Determined by:
egrep -c 'done 201(3|2-?(07|08|09|10|11|12)) $HINT_FILE
It does not count hints, but the little “header” we add above our hints. One header can apply to multiple hints (which is good, because udeb unblocks are usually paired with a regular unblock and we don’t want to count them as two separate hints).
