Love the tool - one question:
I've read that M&M publishes better award availability for its own members than it releases to Star as a whole. However, using the Awards/M&M method returns results termed in YS, CS, and FS. According to the FAQ, these are "normal capacity-restricted Awards" that are "available for redemption across the entire Alliance." However, the availability from Awards/M&M does not match that of Awards/StarAlliance or Awards/AC-StarAlliance for YS, CS, or FS.

Example:
09 MAY 2012, LHR-ZRH 2, seats

Awards/StarAlliance shows FS/ CS- YS- for every nonstop flight
Awards/M&M shows CS+ for every nonstop flight

Do the YS and CS for different methods here mean different things (i.e., different inventory)?
