Hell, Vegeta even scolds the other Saibamen saying that he didn't go all out. So who knows. Equals is probably fine. Yamcha gets too much credit here. Tien also gets too much credit, he is not 1.5x stronger, Piccolo is the only one in that range in my estimation. That punch he lands on it looks devastating, whereas Tien's punch, is not nearly as bad, much different.
This is why I promote getting rid of all scouter numbers. We become indoctrinated with some of these scouter numbers that wouldn't hold up in the debating room. They just get in the way.
