The thing I like about Martin's course is that he's pretty flexible about the way he teaches it and the schedule. Sometimes he may teach the first part on one weekend, wait for the person to practice the kicks, and then teach the second part another weekend - this is what he did with one of the students in our class who was there just for the first 2 days to take the first part.
During our course he also had to attend his father's birthday, which gave me one day to practice the kicks outside the course dives - that's was very helpful for learning the back kick, which is the most difficult one and is fairly difficult to learn imo over just 4 or 5 course dives during which most of the time is spent practicing other things. Martin would also have been willing to take a longer break between the beginning and the end of the course and maybe do a few dives outside of it with us, but I was on a tight schedule because it was the end on my vacation so that wasn't possible.
It would be best to have students roughly on the same level though because then Martin may teach more to that level. If all students are fairly advanced, say returning DIR-F Tech students then he may even kick it up a notch, whereas with complete DIR newbies he'll focus more on the basic basics.
By the way, Florian was the guy shooting the video during our course in January.
