You raise an excellent topic for further discussion.I recall in my stint in Naval Air there was the unit "RCH"........well, you can read for yourself, the first entry:
From my earliest experience, the order of magnitude is this:
- an RCH
- a smidge
- a skosh
- a little bit
- a fair bit
A scad of smidges is a skosh.
After that, you're on your own.
