a TAD the distance between your fingertips and the the saw blade when you miss, and keep your fingertips
a Smidgeon is the amount you saw-burned off when the saw blade touches your finger tips, and you keep your fingertips
a "big ole honkin' chunk" is the tiny amount of your fingertips cut off when you hit deeper than just a saw burn,,,,,,,,,in reality, it is a very tiny amount, but gets described as "big ole honkin' chunk" when the same story keeps getting told, over 30 years later
(TAD is also a term for Temporary Detachment with either another Unit or at another location,,,,,although we always said TDY back in the seventies)
