Style matchups were almost even

49.7% Pushing-style win rate in evenly matched bouts

Conclusion

We retested the favourite idea of style matchups using only bouts where the pre-bout strength indexes were nearly even. Pushing-style rikishi won 49.7%, against 50.3% for belt wrestlers: essentially a coin flip. Individual rivalries matter, but style alone is too small a signal to decide a prediction.

How to read this number

The point of this test is that strength was held constant. Counting every bout, pushing-style rikishi win only 48.2%, but that partly reflects how many strong rikishi prefer the belt. Restricted to bouts where the pre-bout strength indexes were nearly level, the split becomes 49.7% to 50.3%.

In other words, pushing is not weak against the belt; rikishi who take the belt are more often strong. If style itself decided bouts, a gap would survive once strength was equalised.

Individual rikishi certainly have opponents they handle well or badly. What fails here is the idea that a category as broad as pushing versus belt can predict a result. The technique radar on each rikishi page is a better place to look for a wrestler's actual shape.

Methodology

Period
Hatsu 2000 through Natsu 2026
Sample
Makuuchi Kunio divided into two types, push type and four types, using winning techniques until before the bout. Both have type data of 20 wins or more
Even conditions
Before the bout strength-index gap is within 40
Sample size
5,145 bouts
Calculation
Number of wins for Pushing style type rikishi ÷ Number of samples. 49.7%
comparison
Of all 17,921 bouts with no uniform strength, 48.2% were on the push side.

How to read this

A type is updated only by its first WinWinning technique. It's just an average difference, and it doesn't negate the quirks between specific rikishi.
