If the wheel is not laterally true this will not affect the balance by much and if it not radially true it has something we like to call "hop" which something a well built wheel should not have and you don't need much of this to notice it.
I don't deal in fractions when I build and true wheels... I deal in thousandths of an inch with 5/1000 being my usual tolerance for radial and lateral deflection but strive to build 0/0 wheels.
With tolerances like that, I'm certain the wheels you build & true are very fine. The tech that did my wheels I felt did a fine job, I was able to watch him do it as I rode the bike in that day, took him about an hour. As to the tolerances, I couldn't say. I know to the sense of feel in my finger tip, there is very little if any untrueness that remains at the bottom of the tire when fixed to a static position on the frame (seat tube) and fork (the under side of it as the wheel spins thru the fork tines).
"Hop" = imbalance
When you spin your wheel(s), does the valve stem orient itself at the bottom ?
