It will get easier over time, and you will also recognise those people who should and shouldn't be in the training department. Some people will make the sim a better experience where you will learn a lot, and come out feeling as though the session is worthwhile (even if you don't perform at your best).
Other times you will get guys who run the session as if they are trying to replicate attaching a car battery terminal to your genitals. You will get very little from the session from them. These are the people who are usually trying to get more time at home, away from the seniority system, and have little place in the training department.
