And being slightly rather than blatantly off, makes a quarter-inch asymmetry a "subtle but real" ergonomic disaster.
People accept all sorts of strange things in the world as normal, just because they aren't sharp enough to notice -- or worse, go along with "how everybody else does it".
Really? Using that as a tool to analyze significance would have to conclude that one should worry about one's tire pressure being one lb high because if it's 50 lbs high it will explode.
As for your closing statement, though I totally agree with the statement it's irrelevent, as noticing a difference does not in itself argue for changing it.
Part of the deal when you ask advice of knowledgeable people is that you can expect they will inform you of something they are concerned you overlooked. I've done that, you will do what you wish, so good luck.
