Change gear when it feels/sounds right, which you'll pick up

Yup. It isn't that long ago to a time when tachometers were only
fitted in 'sports' or more expensive cars as std equipment.
They have little practical use.

I really disagree. I can make a much more acurate decision about when
to change gear with a rev counter than with my ear. At the bottom of
the rev range this probably translates to a lower incidence of head
gasket failures

How does it stop your headgasket failing?
