The actual formula for how to map # elite years from SPG and MR into MPG has been deemed as proprietary by MAR. We do not really know why but my feeling is to make it harder for account holders to challenge the number of years that they have received. So if someone got their challenge years or other years it could be due to an IT glitch or it could be for some other reason that they decided to comp these years . We will never know for sure and I assume that was the original intention.
