As you can see the number of total unique cards over the total amount is completely wrong compared to the actual number of missing card from every set
The overview total number includes the Deluxe Pack and Promo cards, which are not shown in the bottom. This is probably the reason why the numbers don’t add up. The total number looks reasonably to me if you account for that (especially remembering that there are a lot of foil cards in the deluxe pack)
if that’s the case then probably yes it make sense, it’s just odd to see, considering deluxe ex pack and promo pack are not shown in the main page.
In that case it would be cool, if possible, to also filter the type of pack you want to consider, maybe add a couple of checkbox for the deluxe ex pack type of pack (which most progbably are going to get added every year for every series) and a checkbox for promo “pack”
