@TSBL That’s a tough one. I would imagine that the cards would not change, EXCEPT for instances where a correction to card data was made during the period of time between original and R releases.
I know it does happen, as the community often reports glaring card errors, and the files do get updated with corrections.
But generally, these are one-offs, not a redo of all the original data.
I hope that helps, but like I said, this is really not my area of expertise.
Thanks,
Jeremy
