The quickest way I know how to clock up a machine vice

[Toolmaker51]

Yup, same way this side of the pond!
thehomeengineer shows a bar in the vise and only travels to approximate center of vise [over the center post]. That's all the travel needed for the first few checks. Going all the way across doubles the TIR without any benefit; if the right side is off, so is the left! Always amused watching guys traverse full right and left, especially if there doesn't happen to be power feed, lol.

A few I'll tease with some racing parlance wisecrack about "you collecting lap money?", that an indicator or tachometer, ZIP Codes, if you travel any farther pick up lunch, etc.
It's fun being the old guy!
