6 year continuously losing privileges

Our just turned 6 year old has lost privileges (3 hours when he was 5 and now that he is 6 it is 6 hours) probably 15 times since the week before Christmas. Once he loses his privileges he stays out of control doing whatever he wants to do – many times until he does something that requires a soft hold. (Slamming or throwing things, hitting or pushing someone) A few times he has accepted loss of privileges on his own without being held. I feel like he is almost on a sort of a high in the time between losing his privileges and accepting them when he can “do whatever he wants”.
It seems like when he has been given an instruction to stop doing something he is doing and doesn’t follow it and earns a consequence he would rather go all the way through the rule of 3 to get to the time between losing his privileges and accepting them so he can do the thing he was doing in the first place. He has also lost privileges for walking away in the rule of 3, which he knows is a rule. If he walks away as I am preteaching the rule of 3, but haven’t technically started it yet, is that loss of privileges? He has been doing that often.

He knows how to disagree appropriately and does it often. Is this behavior typical? I’m exhausted and feeling like I’m not doing it right.

Before this recent stretch of privileges being lost almost daily he would lose privileges probably once or twice a week give or take. I’ve gone back through our paperwork from our TSG class and have tweaked a few things like making sure I am pre teaching and explaining what he did or didn’t do to earn a consequence before moving on to the next consequence, which I hadn’t been doing all the time. Help. Thanks Nicholeen.
