I look at a lot of it as drills. I don't think that's how it was intended, originally, but I can't really get myself to believe some of the techniques were ever really going to become go-to for any likely situations. But they do help teach important principles that become useful in adapting the go-to techniques to other situations, or they develop some physical sub-skill (like a speed bag drill does). I try to de-emphasize those parts and guide students to spend more time on the areas that have the most direct application. I looked at removing some techniques, but determined I'd need to come up with other drills to replace what folks learned from them, so they stayed.
