I don't know if anyone at SGC does or not.
In my case, I sent them an Excel document that contained information from several sources - most notably the outstanding back set lists compiled by Ted Z., Scot Reader's "Inside T206" e-book, and the Bill Brown T206 Super Set spreadsheet (thank you to those gentlemen for their research...I hope it's OK that I cribbed from your work!
).
I also looked at SGC pop reports (and even eBay listings) to come up with what I hope is an accurate list to send to them.
