I agree with the sentiment that being nitpicky is why we’re here but it won’t lead to happiness. As they say in watch collecting “the loupe is not your friend,” meaning if you go looking for flaws imperceptible to the naked eye you can always find them. Most of us here are just regular guys. 1/2” or a little bunching will go unnoticed to everyone but our own ocd. The way to find the perfect back fit is to never photograph it or look at it. Get the front fit right and ignore the rest.
