Man, 300 hours sounds like my body's warranty running out all at once.

So the national standard is basically just a suggestion and every tiny town has its own special twist on the rules? That 18 inch clearance thing probably varies block by block depending on which inspector woke up on the wrong side of the bed. I got hit with a setback rule my city added that wasn't in the state code, cost me two weeks and a bunch of new mounting hardware. My new move is making them put the exact code section in the contract so there's no finger pointing later.

The part about "a few duds are just the cost of getting jobs out the door" is what gets me, because I read a thing a while back about how a potter told his teacher he wanted to make perfect pots and the teacher said the A students would get graded on one great pot and the B students on how many they made. The B students ended up with better pots anyway since they learned from all their messed up ones. So maybe the six hour Bible wasn't wasted, it was just the one where you actually learned something the fast batch couldn't teach you.
