USCHO (on its pwr page) has ASTERISKS by UND UMD MICH RPI and Holy Cross.
The note says, "If a team defeats a weak opponent, it is possible for
                its RPI to go down despite the win. Starting in
                2003-04, if this happens in a team's conference
                tournament, that game can be thrown out of the RPI
                calculation for that team. Any team where this has
                occured has been noted below."

Is/are that/those game(s) thrown out of ALL the comparisons, or only
the RPI calculation?  It seems to me that other PWR criteria, most
notably record against common opponents, could change based on how this is
handled.

For example, North Dakota went 4-0 against michigan tech during the
season and 2-0 against them in the playoffs, but those 2 games might
be thrown out.  Does that impact the common opponent value enough
to flip an individual comparison?
