Nice, well thought out, post. One filled w reason, and a member mark for you too.
I agree and i don't believe what some folks say as i've seen them all over the place being well, all over the place. I just like to point out the BS when i see it. Doesn't take a genius to do some simple equations and again, to put some history into perspective.
Best of luck to you.
