Thank you. While I lacked that specific knowledge, my impression was that it was outmoded and, in any event, nothing worth pursuing. So, consider it forgotten.
But, while we are at it, are you able to shed any light on the query about GCKey and Tracker yielding apparently inconsistent results? Is one more authoritative?
Oh, my view between PR Tracker and GCKey is that I think GCKey is more accurate but don't rely too much on those. Either way, we can be sure it is progressing well but patience is always a virtue with the PR processing.
