Sorry, I don't follow. Why 0.5mm? Do you mean because of your hub spacing? Because a spindle which is 1mm longer should move the cranks out 1mm right?

To put it another way, the chainline is close enough to perfect that my calipers and metric tape measure can't detect a chainline different from perfect.
Oh never mind then. Maybe give it a few days to break-in, maybe it's because the chainring is brand new.
