I'm already double DM (250K MQM) on the year and only 118 segments by the end of this week. I'll likely get to 140 segments by the end of this year but it will be very close whereas with MQM's I'll likely be close to 275K by the end of the year. Of course this is also partially due to the triple MQM bonus and a TATL to Mumbai during that time in M but even with most of my travel being domestic I see 140 segments being difficult to achieve. Think about it...

Travel from a hub weekly to one location = 2 segments
50 weeks @ 2 segments = 100 for the year

Even with connections like me via ATL = 4 segments per trip
35 weeks of travel needed to hit 140 segments
