i think the real thought Valiant put out (as he has said a couple of times) is "trying to make card inventory in a comic system". My understanding was the Printing should be thought of as Series, and treated as such. I don't think there is any relationship between printing and season, unless they just happen to line up.
Looking at the checklist site, my judgment would have been the lines would have matched the main title "Stargate SG-1" and "Stargate: Atlantis" being separate runs, with SG-1 being...
Stargate SG-1 Preview Printing 1
Stargate SG-1 Premiere Edition Printing 2
Stargate SG-1 Season 4 Printing 3
Stargate SG-1 Season 5 Printing 4
Stargate SG-1 Season 6 Printing 5
Stargate SG-1 Season 7 Printing 6
Stargate SG-1 Season 8 Printing 7
Stargate SG-1 Season 9 Printing 8
Stargate SG-1 Season 10 Printing 9
I think in the future the filed will be renamed in cards to avoid the confusion of printings. Also, those cards that were reprinted and corrected would be treated as variants (A, B, C, etc) and the Printing/Series would remain the same.
Just my thoughts and understanding.
I have been out of the loop lately, and for that I apologize.
Now, however, this shows how a change in the "system" has become so much more confusing, simply because we started with a system designed to catalogue printed
material (Comics, Graphic Novels/TPBs, Magazines, and Hardbacks) and changed it to catalogue non-printed material (Action Figures, Statues and Busts), appropriately for those
However, cards ARE printed material, and in some cases do have reprintings, which can be handled exactly as comics. Defining cards by Title, Publisher, and Year(s) and leaving the printing field to "factual printing data" for said Title, Publisher, and Year(s).
It is inaccurate to note a 2nd-??? printing that does not actually exist, and would be inaccurate to note a reprint
card as having the same printing as the original release. This not only defies logic, it defies the definition of the word(s), and is contrary to the handling of 2nd print variant comics, especially those that are released to correct editorial or printing errors, as suggested above.
