I think there’s a rules oversight on the choking side of things; while a creature can hold it’s breath for a minimum of 30 seconds (if it has a negative con modifier, which hardly ever comes up), the next paragraph of that rule says: “When a creature runs out of breath or is choking, it can survive for a number of rounds equal to its Constitution modifier (minimum of 1 round).” (emphasis mine) So I’d say that there’s a difference between holding your breath, and being actively strangled- the latter I’d probably rule as a second opposed athletics check during a grapple instead of dealing damage, which puts the creature down after Con Mod consecutive successes.

That is probbaly the way to do. It doesn’t feel right to me. I think. Like, I can find you a video of a six year old choking a processional fighter unconscious in 6-12 seconds. The only strength involved would be getting into that position you know. The air choke thing kinda fits with what we observe in realmlife better than what I woudl ahve thought though. For stuff like arm bars or joint hold manuvers it is almost trivially easy to break someone’s arm with a well placed move. Pro fighters often get injured in training when they are trying not to you know. Which would interfere with somatic components at least. The numbers you talked about make sense in terms of a low-level fighter and a peasant with 1d4 hp. But realistically an arch magus would be just as vulnerable to being triangle chocked by a farm boy as the other farmers he us used to wrestling with at festivals.
