For this one Min. 100 K's which shortened 1981 results. Basically - for a given year, for a player to be in that list they must be among the top 10 K leaders for that year NOT INCLUDING those who would've been listed for a previous year in the quiz. So for 1982, you are looking for players who weren't in the 1980 Top 10, nor those who were in the 1981 Top 10 (a Top 10 which excluded the 1980 Top 10)...and so on. So no player will be listed more than once.
