Luff is the length of the sail, so if you deduct "mast" from "luff" you get the length of the mast extension you need to rig the sail correctly.

rd = reduced diameter, or those newish skinny narrow masts. sd = standard diameter or the things that have been around from last century.

Luff is the measurement of the mast + extension.
So a luff length of 417 means use a 400 mast and extension set to 17cm +/- 1 or 2cms.

RRD or RDM / SRD or SDM refers to the diameter of the mast.
RRD - reduced
SRD - standard
