Has anyone done an analysis of the relationship between PQM and PQD? I admit as a Chase cardholder with platinum status I never paid any real attention to PQD. But this year I have already purchased 92,000 pqm worth of tickets but was surprised to realize it was only about 7500 pqd.

Given the 100000 pqm 12000 pqd you have to average about 8.5 pqm per pqd i only have one flight this year at that level? is it my destinations or is something else at work?
Is the PQD simply set at unrealistic figures for the pqms?
