Again, I say that if the goal is learning to apply technique against committed uke who may or may not resist (according the rules)... what special benefit do I get from points?
Just a thought from a non-Tomiki person. One of the things I've thought about is how to measure progress in a concrete way. Obviously, everyone gets better over time, but it's always just sort of a vague "they fell!" It's pretty intangible even when you do get a belt. Maybe one benefit of keeping score is that it can act as a measure of progress to see improvement. I could see issues with this, but it seems like at least one beneficial aspect.
