Or even one individual on different days. It should be all chaos and noise and yet it's not because these "general" numbers get translated to a realistic "it's more/less likely" not "it's guaranteed".

You're arguing against comparisons you don't like, or feel make you look worse than others. In other words you want to get to arbitrarily define the brush width presumably based on where you feel you sit in the comparison.
