Thanks for the explanation and nice to hear that you have tried this N and K version. I overlooked the possibility of different estimated RTTs on the two sides of a connection. 
Looking in TCP traces one can see that for example Android clients seem to ACK every 2nd segment in the initial phase and later on they typically go down to every 8th segment it does however not seem to be too conclusive and it is difficult to to see in the ACKs are pruned on lower protocol layers, in some cases one can see very long stretch ACKs (up to 100 segments).
