I have final coaches' rankings for 2023 - 2026. But the problem with that is illustrated this year where Iowa had fewer ranked than qualified. For this I used seeds as that is effectively their rankings going into the tournament.
Iowa had by far their best performance relative to their seeds in the 33 seed era.
For finish vs seed I used the mid-point of the range when the range was different than the seed range and zero when it was not.
For example, all wrestlers who were seeded 9 through 12 and lost in the blood round had 0 deviation, but if one finished in the round of 16 (13th through 16th) they are credited with finishing at 14.5 and their finish vs seed equals seed minus 14.5. I point this out because it means the sum of all deviations across a tournament is often slightly different than zero.
