You can see that the outside O44.5 is not perfectly circular (as expected), with the spacing at the widest point (bottom in this illustration) a bit more than 4.25 at 4.5".   Spacing larger is fine, as long as it is nowhere less than 4.25".

I might have to go get my eyeballs re-calibrated.  I'm not seein' it - it looks perfectly circular and concentric to me.
