And reentering the correct Tool offset has a habit of correcting things

Yeah, well if you could get over yourself, and read, you would know that the offset was correct.
It was probed.
Then it was re-probed.
Then everything was calibrated.
Then it was probed again.
Still glitched.
It didn't behave right until the offset table was wiped.
The exact same numbers are in the table now, as when it was acting up.
Photos of the offset table are here, in this thread, for all to see.

It's really not that challenging of a concept to grasp.
