I have a different approach on the new courses.
With my 40+ years of teaching experience, presenting ROBS, CAS & WBAS in 5-6 hours is just that "Presenting". That is all there is time to do.
Combined the three courses have 327 slides not including the test question slides. [See comments below for correction] That is about 11 seconds per slide. Yes, some slides are just titles and many slides have multiple levels (bullet points).
In my experience, it is the discussions that have the greatest value. Especially from the senior shooters. Together the senior shooters likely have more experience and real-time examples than the person in the front of the room. As the trainer, I see my role as guiding the comments of the senior shooters along with the slides.
I did present-teach all three on one day. We started at 8AM, finished at 4:30PM with a working lunch. It was commented that it was a L O N G day. My preference would be ROBS one day and CAS - WBAS on another day which would include live fire on range, stage design and holding the clock.
