The art of being so small you're legally and scientifically allowed to not count.

means The quality of being small or unimportant enough to be safely ignored or left out of a calculation.

from Traces back to Latin neglegere, 'to disregard or not pick up' — itself built from nec ('not') and legere ('to gather, pick, choose'). The '-ibility' ending bolted on later, turning 'can be neglected' into a measurable property, the kind scientists and accountants love to round down to zero.
