it's not just the range...it is also the assumptions and conditions you impose in those ranges as well.
Exactly. Anyone ever try to use judo against a guy in a t-shirt who refuses to try to grip you and instead hops around and shoots singles and doubles?
It's damn annoying. Even moving from gi to no gi has unique challenges to it. I never realized how much I use the gi in my day to day game. I had to spend a lot of time relearning very basic concepts to get my game up to the same level. Even simple stuff like breaking posture has to be done differently. Most of my favorite chokes all use the gi. The advantage is just learning how to blend what you know on the fly for any ruleset.
