I think some safety fallback would be better. Like

Probably. And yes, it should still work since stop>start at all times.

And couldn't TSF counter overflow during the measurement?

Yes, if the card has been up for like 459148 years or has been reset to
an unbelievably high value. Remember, it's a 64 bit counter.
