If it's "in the eye of the beholder", then there is no objective reference to say whether any difference actually exists.
You still don't get it - "in the eye of the beholder" refers to the presentation of evidence by the author of the position - you may retort with a qualitative argument but you are attempting to retort with a quantitative argument and it is not working.
You still don't understand the difference between qualitative and quantitative and so you are relegated to the "PeeWee Herman" style retorts: "Is not...is not...is not...is not..."
