There are many areas of a bike that sub-millimeter differences make a difference but I contend that in this area it is not that critical. I rode 30 miles today and never had a hitch with the seatpost. Please get down off your high horse.

I'd worry more about metal fatigue at the top of the seat tube over the next 3000 or 30,000 miles because the seat post is only fully supported there instead of along its entire length.

There's no point in trying to respond with useless factual information like that. He tried it and it works "today". He may really be fine depending on rider weight and how the bike is used but I stand by my assertion that we provide answers to the best of our abilities on the right way to do things. The answers benefit the OP, if they choose to act on them as well as any other readers who may learn from them. My only real objection was this post:

I read that has Hey smart _____ses,
looks like I was right and you were wrong, it works just fine and he follows my post with "I have asked plenty of questions and taken advice "19 posts total so far" Maybe I'm just being cranky but I read some attitude there.
