Good catch!

More details on what to check:

This is repeatable, and all come out the same, like it was meant to be, how do I attach image?

AFAICT, the `Scanning Offset Adjustment` corrects for the constant-ish time delay through the HV power supply that causes a linearly increasing offset with speed.

Mechanical backlash would be constant with speed, so the offset would remain the same. I _think_ the `Initial Offset` value could compensate for backlash, but it’s likely to decrease linearly with speed.
