DL published their avgs (1/2014-10/2015) -

Civ 7700 TT 4100 PIC
Mil 3100 2200


UA and AA have released some data but it's not as detailed -

UA 2014 - combined avg 8600. Mil - 3500.

AA was sub 6000 TT for all? Can't find the fact sheet. AA published their f/t TT. Average that into the class breakdown (80% +/- military for non f/t's) and the TT estimate might be closer 7,000(?).
