Effects of "no" at the beginning of a conditional statement

So you may not like this, but I'm going to try:

I would encourage you to just think about it logically. What you wrote is this:

If you haven't become a champion (~BC) then you must not have superior mastery (~SM). But that makes no sense. Obviously no mastery is ONE reason you might not become a champion, but there would be a billion other ways to fail (i.e. not being interested in competition, freak accident, illness etc.)

The other way says If you're a champion (BC) you must have super mastery (SM). This makes sense, because we know that mastery is a condition for championhood.

I only make this point because I don't like people to get too attracted to purely codified ways of diagramming. I think it's best to keep your logical brain on. That being said, if X is a necessary condition of Y, then Y --> X. That would be the direct, eternal truth.
