Explanation Of Quality Win Factor (QWF)
Teams are awarded certain quality points for defeating a team ranked 1-5, 6-10, 11-20, and 21-59. The higher the 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
So how do we determine which teams are in which groups (1-5,6-10,etc.), we employ two alternatives: we use the RPI ranking from the RPI method, or the power ranking from he power rating method. 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
1-5 6-10 11-20 21-59

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. We present both results for comparison below on the printable link.
