You're right that Card Ladder has only been around for a few years - looks like they started in June 2020.

But I assume they collect sales data that goes back further. My experience is that data from 2010-today is fairly abundant, data from 2000-2010 tends to be less abundant, and before that is really sparse. So I wouldn't be surprised if they're picking up data from the last decade or so, and maybe attempting to go even further back, although I would be suspicious of just how precise any data will be prior to about 2010.
