Using the spreadsheet, the Q map graphics, various .PDF files floating around, and the Github page, I've compiled a comprehensive list of Q messages that is 99.999% certain to be missing nothing. The problem is that no other source has everything. The Q map graphics are missing the first x number of messages - maybe the first 13, maybe the first 2 or 3; depends on which version you look at. No source for info agrees with any other. It's a free-for-all. The GitHub page keeps changing - the count seems to be different every week. Now it's at a new low of 410 messages so a lot were pulled off and I don't know why.
I think the graphic will ultimately be critical, but right now there just aren't very many people who are concerned with it. Since you can remove excess info at any time, but you can't add it without the original source data, I'm just including everything for the first completion. I myself am missing 14 messages from the one I just did - which I thought was complete. So the first "okay I'm done" official new Q map will go out with 451 messages on it. They're ordered by date/time of posting. There is no other correct source for this. What happens after can be worked with as needs require.
My prior huge Q map had 437 messages. My current result from all the comparing I've done is 451 unique messages; that's what I have. The spreadsheet has a lot of ordering and typo problems but everything seems to be present in it.
