QUALITY WINS FACTOR (QWF) EXPLANATION


QWF based on RPI
The RPI ranking could be used to determine quality points. In this case, teams are awarded
certain points for defeating a team ranked 1-5, 6-10, 11-20, and 21-59 in the RPI rankings
(to use ranges that would be applicable to Men's Division I lacrosse). The higher the RPI
ranking (e.g., 1-5), the more points they receive. Also, teams are awarded negative points
if they lose games in which the reverse applies. That is, losing to a lower-ranked team
results in a loss of points. Here's the scheme:

  Defeating a 1-5 ranked team yields 25 points
  Defeating a 6-10 ranked team yields 20 points
  Defeating an 11-20 ranked team yields 15 points
  Defeating a team ranked > 20 yield 5 points

  Losing to a 1-5 ranked team costs 5 points
  Losing to a 6-10 ranked team costs 15 points
  Losing to an 11-20 ranked team costs 20 points
  Losing to a team ranked > 20 costs 25 points

Using this system and looking at the example below, Syracuse's points would be computed as
follows: 

QWF Points = (4*25 - 1*5) + (1*20 - 1*15) + (4*15 - 0*20) + (7*5 - 0*25) = 195

20 Villanova        -35  0  1  1  2  0  1 10  2

The more difficult the competition the greater the reward for winning and likewise a loss 
to a weaker team results in a greater penalty than losing to a stronger team.
