When you say logical supports, do you mean something like "A because B and C"? Why is this better than a graph?

If you can't tell I don't know much about formal logic. Apologies for the naive questions.

I'm not saying it's better. I'm saying I've thought of a similar idea but with a different notation.

I didn't mean to come across as argumentative, I was just looking for more details so I could understand better.

Oh, you didn't. I did. Sorry - mind on other things!
