Good precedent for this. Tukey used fourths, eighths, 
sixteenths, etc., for _one_ way of calculating such measures: 
except that noting the sequence Fourth, Eighth, ..., he 
switched to letter values D, C, B, A, Z, Y, etc. 

The whole idea is encapsulated in Stata's -lv-. Somehow, 
it has never quite made it to mainstream, I suspect.
