RE: What's the difference!!??
My thoughts are that if it were I, a lowly peasant, who posted this thread I would be ripped to shreds. But since you are an idol of many including mine, I think you're safe. LOL I'm only half way kidding.
It is the way in which you arranged and presented your thoughts that make it easier to understand where you're coming from. I agree, if you are proficient with both out to 20, there's not a whole lot of difference in my "traditional"ly inexperienced eyes.
