Installed a couple of Argos items last week. When I say installed, I
mean hung on the wall.

First was a large mirror. Two 'upside down keyhole' brackets with a
recess behind them. *Simple. *Measure the distance between them, divide
by 2, mark centre line on wall, draw horizontal line, drill 2 accurate
holes.

This method of fixing is generally a PITA because you have to get the
holes 100% spot on - there is no adjustment or 'play'.

Distance between fixing centres? 91.5cm. *Divide by 2 = 47.75cm! *FFS
why not just make it 92 cm? *Or 90cm?

How do you think that would help?

Because whole numbers are easier to read off a tape.

All my tapes have clear graduations every mm. You should be aiming for
at least mm accuracy, i.e., 91.5/2 use 45.7 or 45.8mm. 92/2 would be
46.0mm, not 46mm.
