IIRC shoot boxing clinch time is at the discretion of judges, and multiple knees are allowed.
Well, in the present unified rules, the clinch time is five seconds, repeated knees are allowed, but knees to the face aren't allowed.
The thing I don't like about Sanda unified rules is that the scoring criteria removes suplexes, sacrifice throws, and landing on top of thrown opponents, which are highly destructive and effective techniques. Less points for landing on top of opponents in ammy Sanda is bollocks in my opinion too, as landing on top of an opponent usually does more damage than a "clean" throw. But then again, I suppose that opens the argument of technical superiority versus actually dealing damage!
Thanks. Ya, unified rules and even pro-sanda to some extent really killed the wrestling. Also, in "ammy sanda" going to the ground with an opponent is actually fine if its above the hip, if the opponent's feet shoots up in the air when they land, or if its a high difficulty level throw (like the scissor takedown), which will score 3 points regardless of whether you remain on the feet. Basically, in standard Sanda those high altitude "shoot points" of Shootboxing score three points, not just one or two (I think in king of sanda that was the rule too, don't know about CFC). Whereas takedowns below the hip score 2 if you remain standing, and one if you go to the ground with the guy. The idea is to keep yourself standing (this is a traditional self defense ideology; you never want to be on your back).

Not much more for low altitude throws...also the idea to to keep yourself standing is so you could stomp and kick the downed opponent(a traditional MA idea) and the fact that you are more vulnerable if you go down with the guy (scrambles, weapons and submissions).
Basically, shootboxing is still a striking based ruleset whereas slams score the same as basic punches, whereas standard sanda is more grappling focused where minor takedowns score the same as punches and kicks and slams score more than all, and it's 50/50 between striking and grappling. Old unified rules are fine but the new ones since 2009 does kill this to basically appease the Thai, so that's why I suggest bringing it back to score 3 or at least 2 points, so its more wrestling based.
Also, you can never truly reflect the damage of throws on a mat! Even slams rarely knock people out if they know how to fall on soft mats.
