Your explanation makes sense. It is simply a lack of processing capacity on the part of the hardware. That's why it's cumulative.
I suppose it becomes more evident with clips within loops, and less so in clips intersected by the loop, simply because it does not have to calculate the beginning and end cuts of the clip.
Stop playback for a few seconds and resume syncing again.
As for random artifacts at the end and beginning of small loops, I have found that adding the minimum fade in/out type increasing decreasing eliminates them without the fade being perceptible.

Possibly they are different things.
