The amount of wash out rate that picked up last year has nothing to do with only having 4 sims. Most of those guys were already struggling during the CBT or FTD portion. If you go back 2-3 years it's rare to see anyone wash out, you can usually see it coming before that person even get to the sim portion. Having 8-10 sims probably wouldn't have a made a difference to some of these guys. This is from what i've observed from our training department.
