I wonder how much expectation influences perception, i.e., if the stated scale on the box is 1/25, but the kit actually scales out to something different, would it still look 'just right'. I recall an ancient kit (Monogram coincidentally) of a popular aircraft subject was stated to be 1/48 scale. It was the only kit available of the subject in that scale for decades and several companies offered dedicated aftermarket accessories/upgrades for it. Someone finally measured the actual airplane and discovered the kit actually scaled out to 1/51. Surprisingly, the fact that the kit is oddly scaled was almost universally dismissed by modelers that had previously professed strict adherence to scale fidelity and many comments along the lines of ' well, it still looks like a T-28' were made'. Ironically, a few years ago a Ukrainian company released a kit of the same subject that was a true 1/48 scale. That kit proved to be much less popular than the old Monogram kit despite being far more detailed and accurate which causes me to wonder how much nostalgia plays a role in perception.
