Nice man.
I wanted to say that I would have had a difficult time answering the first one actually. I see unit surfing as low degrees turning per sec with low std. tech as high degrees turning per sec with low std as well. oldschool as any degree turning per sec with high std. I prefer old-school with medium+ degrees turning per sec.
surf_egypt2 is kinda my ideal map style IF it wasn't for the disaster that you couldn't see the ramps because Mariowned wanted to make everything be natural (but you just gotta accept that surfing ramps is not natural. well obv. that would have destroyed the aesthetics, but well, who says aesthetics have to be "naturalism". he could have tried to make it look like a piece of abstract art of pyramides and ancient Egypt instead haha)
honestly, I don't know how accurate my categorization is, but would you call surf_vegetables for tech surfing? Hmmm,
well, in general, it is very hard to categorize. maybe "varied" could have been the third category.
In general, it's very difficult to put down in categorizations. But I understood that you had to do that for your survey obv. It's tough.
Number of strafes per second is also interesting, e.g., surf_portal s1, https://www.youtube.com/watch?v=oVEu0QtID1I which also connects to rampstrafes maybe.
"max vel" is more like a surf technique, e.g., "rampstrafe" should then also have stood there.
