Do rikishi tend to lose after a kinboshi?

Conclusion

After an unranked rikishi defeats a Yokozuna for a kinboshi, his next-day win rate is 38.0%, ten points below his rate on other days of that basho. The next opponent is often another elite rikishi, so the result reflects both the emotional aftermath and a difficult schedule.
