Same, I figured this was the least-controversial variation that I posted.

It's interesting that you don't see these suffixes as a spectrum. I thought it was a good example of a spectrum of something like "increasing belief on my part that this thing can or should be described by this noun", from -qoq ("obviously not such a thing") to -na' ("definitely such a thing"). That's a good point about how they apply at the time of speaking, though. (At first I was going to argue that in the right context they could be taken to mean "what I thought of them at the time", like if they were contrasted with each other in some kind of temporal sequence, but I think that's mostly just because I really liked that example and want to salvage it somehow.)

Same reaction as with the time stamps. 'awje' (ok) qa'vIn (still going?) wornagh (wow, all that?!) DItlhutlhtaH. But this one really wouldn't make any difference if you conjoined them with je: the sense of sequence is not very strong.

This is also the example I liked least.

The concept isn't "sequence"; it's "thing that changes in this sequential way."
