My comment on this is a bit ambiguous. The best way to understand the PWR
is to look at a particular comparison. I display all comparisons between
Teams Under Considerations (TUC) on USCHO. Since BU vs UNH was mentioned
here it is
Boston University vs New Hampshire
RPI 0.5757 0 0.6052 1
L20 12- 3- 5 0 16- 4- 0 1
TUC 3- 3- 1 0 6- 6- 0 0
H2H 2 0
COP 7- 3- 3 0 10- 2- 0 1
============================================
PTS 2 3
Key:
RPI -- Ratings Percentage Index
L20 -- Record in Last 20 Games
TUC -- Record vs Teams Under Consideration
H2H -- Head to Head
COP -- Record vs Common Opponents
Notice that BU got 2 points for its two wins vs UNH, but UNH
won the overall comparison 3 to 2 and those gets "1 OVERALL comparison
win". Thus a "comparison" consists of the 5 criteria and each comparison
won by a team is worth one point.
