Playing without form may not be for everyone but it is for champions. We can see how each gripping strategy effects the player's ability to move and attack. To evaluate effectiveness we need to determine who uses the gripping strategies. During the elimination rounds we see a neutral distribution of gripping strategies. Distribution of gripping strategies is neutral because players of all skill levels are indiscriminately mixed.
Preliminary rounds eliminate the weakest players of the day.
The quarterfinal matches set aside the stronger players for the medal rounds. The combination of preliminary rounds and the quarterfinals leaves the second echelon players to compete in the repechage for a chance to advance into the bronze medal round. Distribution of gripping strategies will remain mixed, with weight towards secondarily effective gripping strategies. In other words, the best players in the repechage use a gripping strategy that may not be effective against elite players but it will win through to a chance for the bronze. Elite rounds include quarterfinals, semi-finals, bronze medal matches and finals.
