The whole things hard to judge because there's a good chance he is just using that drill for a bad weight cut.
I was shocked a few weeks ago at hearing DC on a podcast talk about how fighters used to cut massive weight the night before and go to bed about 1 pound over. He was saying that now a lot of fighters go to bed the night before 8-10 pounds overweight still and cutting weight very hard the morning of weigh-ins. He said their reasoning is that when you do the massive cut the day before weigh-ins that you get a very poor quality of sleep so they now just risk the cut going bad the day of to have a higher quality of sleep in the nights leading up to the fight.
I'm not sure if DC was talking about an outlier or if that's truly what fighters are doing now compared to the past. But if what DC says is true it makes sense that we seem to have a lot more cancelled fights in the final 24-30 hours than in the past.
