By my count HHH's total cumalitive record over the past year is 24-16-2. In singles matches he is 20-8-1 and 4-6-1 in tag matches.
In singles matches where there was a "clean" finish HHH was 14-3. In singles matches with a "dusty" finish HHH was 6-5.
HHH's three clean losses were in a match with the Undertaker where Rock interferred but did not have a direct effect on the pinfall, which is why I considered it a clean loss although suspect, and two matches with Shawn Michaels which were in essentially a street fight match and a gimmick match. He has been pinned clean twice in tag matches by Rob Van Dam & Booker T. So HHH has not lost a match clean that was a straight 1-on-1 match with no gimmicks, no stipulations, no interference in the past year.
