I don’t have an answer but I have experienced something like this. I took a BIAB track to the pro recording studio I use. My track was tempo quarter note = 140 bpm. The engineer determined it was actually 139.6 something. We stretched it to a true 140 as measured by his hardware word clock.

What is different in your case is you have said there are, for lack of a better word, glitches at certain places. I did not experience this; my tempo seemed stable, just not precisely right.

I don’t know if software has a mechanism to sync to a word clock, nor which software does so if it even is possible. And my home setup, while quite good, does not have hardware that would sync to a word clock. It’s an area I would like to know more about.
