I've been using the sim for a while and like it a lot.
However, there is a discrepancy between your build times and the ones shown in (elite) barracks...
Marksman: 200 sec (3:20) in barracks vs. 300 sec (5:00) in FastSim
Mounted Marksman: 300 sec (5:00) in barracks vs. 200 sec (3:20) in FastSim
All other (elite) troops seem to be fine.
