Delta can't do arithmetic
Looking at my SkyMiles statement for 2009, the total in the MQM column is about 71,000. The statement for 2010 starts with 21,824 Rollover.
Adding up the MQMs for 2010, I get about 137,000 (including the rollover).
At the top of the page, it says that total MQMs year-to-date are about 101,000, including about 11,000 rollover.
Unfortunately, the stuff at the top is correct. The stuff shown in the details is Just Rong. Why can't they show the actual numbers they're using to compute the totals?
