Wow. That is some mighty fine math going there. You lost me at V1=pi. I mean, I thought I was smoking tobacco, not pie.
Well, anyway, 1oz of tobacco will take me roughly two weeks. I just don't get to smoke that often because I have to go outside to smoke, which usally means I have to carry laptop, matches, tobacco, ashtray, pipes to the deck. Then something will happen, like a tree will fall or some cat emergency will ensue and my pipe smoking is doine for the day.
Yeah, I need a smoking vacation, then I might figure out how much pi I can smoke
