LOL!
I bet if I look up "putz" in the dictionary there's a full page photo of you.
Wearing a sombrero.
And you're still as FOS as a Christmas turkey. I've never used "calculations" to decide which bullet to use. I know you can't fathom such a thing, but try to wrap your pointy little sombrero wearing head around that.
And seriously, kids throwing rocks? I was pretty good at throwing rocks as a kid, still am. But I never needed any "calculations" to do it.
I wouldn't be surprised if you whipped out a calculator every time you wanted to throw a rock but I'm thinking it didn't help any.
