I heard from Karl this morning. From the tone of it, I think he was frustrated that he couldn't give me a better answer. The bottom line is they believe that the mislabeling issue is sorted out as of 11/1/18 production but before that, he can't say which ones may be incorrect.
So, especially with labeled C12-4s, I'd not fly pre 11/1/18 ones in a model that a full six-second delay would cause a crash or near crash, though I have flown some that were correct (or looked that way in models I didn't have an AltimeterThree aboard) as well as ones which clearly ran long (and were likely really C12-6s).
I can also say that post 11/1/18 motors are out there as I got some C12-4s from jonrocket.com fairly recently that are 11/13/18 and a pack of D12-6s that are 11/1/18.
