Mark, thanks for the 5 stars! We're glad you liked your training!
The training was very thorough within the bounds of the stated objectives. I have seen recap statements with similar training in the past, that might have been a nice reinforcement tool. It did move rather fast. Fortunately, having had similar training in the past the main points were well understood.
