Mike Bohn of MMA Junkie has been charting this since the start. If you look at the two-year period from June 6, 2014 to May 30, 2016, the final two years with the weigh-ins coming late afternoon or early evening the day before the fight, 32 fighters missed weight and five of those had issues that led to them not fighting. In those 27 fights, the fighters who missed weight went 12-15, so there was no real edge gained on average.
Over the past two years, with almost exactly the same number of fights (the 2014 to 2016 period covered 950 fights while the 2016 to 2018 period covered 962), from June 4, 2017, the first show under the new system, until this past Friday’s show, there were 62 fighters who missed weight and 15 of them had issues that resulted in fights being canceled. Of those who did fight, they went 27-20. Notably there was no real edge until this past year, when fighters who missed weight have won almost every fight.
It was almost double the amount that missed weight
So weird since it seemingly made things easier
