The girls are not trained so not skilled or strong enough for KO, I'd say it's more like Extreme Catfights with punching and kicking allowed but not the focus as have dirty catfighting moves also being used with some grappling thrown in. If looking for KO's Female Muay Thai is great as get many KO's when knees and elbows are allowed with the punching and kicking!
I don't remember KO's in Crystal Mags but they were going all out. The way women lock up with hairpulling makes KO's rare in catfights.
