I do not think it is significant. However it does have this flaw. TBH the best I ever measured was a jet saw fence it was near perfect.
My other saw, I just reversed the fence board to the other side and it made both better, might try that.
One other thought, all wood moves, so keep that perspective when trying to attain perfection. Besides I keep my back fence set roughly. 005 wider anyway.
Most my observations are just That, observations.
