December 16, 2019 WrestlingByPirate Dual Impact Index (and explainer)

Here’s how the numbers are calculated:

Individual rankings: Basically, all wrestlers set to 100 at the start of the calculation, and the opponents’ rankings having 30, 40, 50, or 60, depending on the type of victory (to correspond with dual scoring), either added or subtracted from it in each cycle. When the numbers stabilize to three digits (the one-thousandths place), the rankings are finalized for the week.

Minimum numbers of matches for the season to be listed remain at five at the weight against Division I opponents, however, it is also a requirement that a wrestler participate in a single-entry tournament or dual meet, attached. Wrestlers who have met the five-match requirement, but not the single-entry requirement, are listed in red. Wrestlers who have met both requirements, but are not the best wrestler at the weight on their team, are listed in yellow.

Dual-Results (yet to debut):

Based on the results of duals themselves. Figured the same way as the individual rankings, with each team being given +/- 30 points for a win or a loss, plus or minus one point for each match the dual is won or lost by. Criteria points are not included in this figure.

Tournament-Strength (yet to debut):

Teams are given points on the same scale points are earned at the NCAA Championships, with bonus points.

Dual-Component (yet to debut):

Teams are matched up in mock duals based on how the individual wrestlers are rated. Bonus points are given at a margin of 35, 45, and 55 points, to simulate major decisions, technical falls, and falls, respectively. The number listed is the number of mock duals won.

Roster-Component (yet to debut):

Similar to the Dual-Component ranking, but includes redshirts. Basically, what things might look like if every single coach in the country pulled all of their wrestlers out of redshirt.


WL: Based on only wins and losses (Dual-Results only)
MOV: Based on only margin of victory/scoring of bonus points (Dual-Results only)
SOS: Strength of Schedule
Total: Win/Loss plus MOV (Dual-Results only)
