Whenever I watch a match I keep track of who I think is controlling the center, rather than who looks most active. And about 90% of the time I wind up in agreement with the call by the ref. Trying to think back after thr call is made is too hard and filled with bias from all that "action".
One thing I think I have noticed is that US wrestlers like to circle and look for angles. While this may prove ultimately fruitful for scoring, it is the exact opposite of how the poorly named, but effectively used, passivity rule is written.
