I suppose it depends on what is meant by “technique”. If the definition means a certain type of punch or kick or joint lock, vs. a more lengthy scripted “self-defense situational technique” similar to what is found in the American kenpo lineages, that is a whole different animal. Either way, a deeper focus on fewer seems more appropriate to a seminar, in my opinion.I could see it being useful, in select circumstances. The first is if it's meant as more of a showcase, if you are trying to decide what interests you and what type of art you are going to pursue (normally I'd say this to be broken between different people, but John has experience in a lot of different chinese arts, so he could accomplish that on his own).
The second is if you are working with that instructor regularly, or another instructor who has similar knowledge, so you can later delve deep into the techniques that interest you.
My preference, though, would still be significantly less techniques - maybe 10 so you get 15 minutes per technique (with some built-in buffer time).
