Correct. The time per division is done as time per major division.

Correct.

There is a variable control on the time base setting, IIRC the knob that is
concentric with the time/div switch. Make sure this is in the calibrated
position. If it is not, then the time/div will always be longer. The
variable control has a detent on the calibrated end of its travel so that it
will always lock in and not be easily moved off. There may also be an
indicator lamp near the time/div calibration to show when the variable knob
is off the calibrated position.

With the variable knob locked in the calibrated position you should then be
able to adjust the screwdriver adjustment to calibrate the timebase.
