I think there will be more people listing their collections in full, if they believe that there is a posibility of reach the 100% of a particular year, but if every now & then a card that is not part of the regular production is added to the list the percentage goes down instead of increase making almost impossible to reach the 100%. In my opinion every backdoor card, proof card, error card etc should go on the "odd"ball" list. What are the odds of find an error card that is not part of the regular production, one in a million? I have like 10 different backdoor press plates that are not listed, i don't care if they are listed or not, nor the procedence of them. Let's make possible to reach the top on the main list, and list everything else on the oddball list. No offense!
