I’m guessing you’re a dentist, but as you know there’s a reason why medical researchers put more credence in studies that lasted decades rather one that lasted just months ( e.g. Framingham). Stock analysts apply this same concept. And if people are equating cards to stocks then this should hold true as well.
i certainly agree with you regarding quality of data...and yes...i'm a dentist. I just think it's funny how many want sports card collecting to be a pure..."perfect" marketplace...but it can never be. There are too many variables...combined with all data not being known/available.

Sooooooo...we just have to live with the data we have.

And...maybe...baseball cards shouldn't be viewed quite so much as stocks????
