"nobody looking is going to care. most people who see these displays arent "impressed" with our nerdiness, and arent giving us extra points for our ocd to keep everything in scale."
I don't collect for other people. I collect for myself. My desire for a consistent scale has nothing to do with impressing anyone with my nerdiness or earning extra points. Just because scale doesn't matter to you or collectors like you, that doesn't mean people who care about scale are out to impress or score brownie points.
As collectors we all have preferences. There is no need to dismiss another collectors preference for uniform scales in their collection if that's what they like. My collection is for me. I roll with whatever works for me and my tastes/preferences. Every collector should do the same.
