Thanks rickair... that makes a lot more sense. My employer has our students log Sim/FTD and Dual for instruction that occurs in the sim, and then we subtract that Dual back out when they do their 8710s. It seems like it's adding a needless extra step to me, but what can I say... they like paperwork here.
Since I trained at the same place I work, my FTD time is logged this way as well. I guess if asked in an interview, I'll just explain the logging method.
