Given the influx of submissions lately, myself included, I was interested in potentially writing some code that would track the Pop Report for WOTC sets.
I don’t know how often these Pop Reports are updated though. I imagine once your card is graded and sent out it’s adjusted but I could also see it being a one time end of the month batch thing.
Actually after having looked at it I still think I would do something a bit different, which is a time series of population increase for a given card. Unless that’s available and I’m missing that somehow
Maybe there is a misunderstanding between us, but I think the thing you mean is available on pokemonprice. When you select the “population chart” tab you see the pop for a given grade on a given day.
