I think it's fine that it's a limited course. If you're qualified to dive Nitrox 32 and 36 to 20m max using air tables or an air computer, then do you need complicated formulae?

If you're "qualified to dive Nitrox 32 and 36 to 20m max using air tables or an air computer" then why not just dive air?

I admit that I haven't read the course notes in detail, but I fail to see any real point in diving nitrox as if it were air within Ocean Diver limits. Given that these are single-tank, inexperienced divers, whose bottom times are likely to be limited by the gas they can carry (and the rate that they breath) rather than their NDL, then what's the benefit?
