Below are listed the YAM2 rankings as of the end of last weekend
(1/13/96).   An explanation of the YAM2 system has been included at the end
of the ranking tables.  If some of you are viewing this table using a
proportional font for display,  try switching to a constant pitch font.   It
will look a lot cleaner.

     The YAM2 is an intuitively based simple formula which seeks to measure
accomplishment over the course of a season.  It will not identify the teams
which are currently hot,  but views the season as a whole.
 
     YAM2 differs from the Rating Percentage Index in its relationship
between the Win% and the metric for Strength of Schedule.   In YAM2,  this
is a multiplicative relationship,  whereas in the RPI it is additive.
 
          YAM2  =  (Win%)  x  (Strength of Schedule)
 
     Strength of Schedule is defined in the same way as in the *old* RPI:
 namely 2 parts Opp% added to 1 part Opp-Opp%.  In this implementation,  the
strength of schedule is normalized to the value of the strongest schedule
(Minnesota this week).  Also,  as in the RPI,  the head-to-head games are
subtracted from the records before calculating the Opp% in order to prevent
"inverse" effects on the ranking metric.
 
     YAM2 gives equal *mathematical* weight to Win% and Strength of
Schedule.  However,  since Strength of Schedule inherently varies less than
Win%,  SOS will produce less effect than Win% upon the ranking placements
(approximately plus or minus 5 positions,  maximum,  from experience).
 
     As a property of the multiplicative relationship between Win% and
Strength of Schedule,  YAM2 will not produce "inverse" ranking effects.  For
instance,  it will not raise a ranking if a team goes to Minnesota and loses
two games (except in *very* unusual circumstances.
 
     Have a happy MLK day,  everyone!
