Doesn't that require you to tram the head each and every time?
Tilting heads always seemed time consuming to me.

Yep, but with a tramming indicator (that itself has been 'trammed' to
zero, then handled with kid gloves), and some practice it takes maybe two
minutes. You don't take an absolute reading, anyway, but the average of
the two 180 apart, if they're reading a tenth or two out.
