It’s real. My department had the “rule of 3”... not 10. I believe that areas with larger populations can use a rule of 10.
So if it goes A, A, B, B, B, C, C, C, C, D, F, F, and you can only take 4 guys on you would get the four groups:
A, A, B
B, B, C,
C, C, C,
D, F, F,
Hire the first in each and end up with one A one B one C and one D?!
Or did they not bother with the scores at all unless some lawyer came poking around and just went strictly by color/patronage?
“Its real. My department had the rule of 3...”
So did mine.
