Glad you're having fun with this "internet stuff."
I would have to say I have to work on a whole bunch of stuff in grappling and other things! Again, I am believer in preparing for the as much of the contingencies as possible (besides it's fun.) But definitely will take your advice on the rear naked choke.
I think your percentages are interesting. I wouldn't disagree with the need to learn those components but I am not sure if I agree with the weighted percentages. Probably because in recent years, I am more concerned with and hear more about "steet predator" types rather than say fights in a club or bar. Their M.O. is to get your money ASAP with minimal fuss and get out. An extended fight is not what they want. Generally, they want to sucker someone or come with a weapon. Striking with or without a weapon seems to be preferred. Of course, women face a different type of predation. Certainly, grappling would be helpful to counter that. Anyway, your percentages certainly are something for folks to mull over.
