In the real world, eyeballing is fine. With a little practice (learning a few
of the stranger bottles) you'll be accurate +/- 5% . That is entirely good
enough. Hey, +/- 10% is OK too,
- because it evens out just fine.
- because you are re-calibrated every time a bottle changes, so you can never
be too far out!
- because it's not worth the extra time and hassle to be more precise.
In practice, we just stocktake to 1/10 of a bottle.
so you've got 20 bottles of vodka at the start of the night, and at the end
you've got 7 and (about) 6/10
Assuming your eyeballing is only accurate to tenths of a bottle ...
that's 7.6/20.0 +/- 0.1
= possibly inaccurate by up to 1% !
AKA 99% accurate.
NOT WORTH WORRYING ABOUT
If you still care (or have a bean-counting idiot for a manager) you can learn
how to weigh them. Keyword: "tare weight"
(I'm a bean-counter sometimes. That's why I did the maths long ago and figured
out which parts of my stock control were not a real problem)
