Of the 2,189 McNair profiles on WikiTree, five are currently marked as unsourced, leaving an improbably high 2,184 profiles (99.8%) at least supposedly sourced. The percentage of McNair profiles from the Commonwealth War Games Commission, ThePeerage.com, Veterans Legacy Memorial, Wikipedia, and our watchlists that have at least one primary source currently stand at 50%, 57.1%, 100%, 100%, and 100%, respectively.
The average sourcing level for McNairs from the Commonwealth War Games Commission, ThePeerage.com, Veterans Legacy Memorial, Wikipedia, and our watchlists currently stand at 1.0, 1.9, 1.7, 2.2, and 1.7, respectively.
The number of "tallied" profiles (the Commonwealth War Games Commission, ThePeerage.com, Veterans Legacy Memorial, Wikipedia, and our watchlists) with no sources (level 0) increased by one since last June. The number with no primary sources (level 0.5) increased by three. The number with one primary source (level 1) increased by one. The number with two primary sources (level 2) increased by two. The number with three or more primary sources (level 3) increased by three.
The percentage of all McNair profiles on WikiTree which are partially sourced barely show as a thin light orange line in the chart. For the tallied profiles, I depend on the counts in my spreadsheet, where I assign sourcing levels as I check the profiles. For WikiTree as a whole, I depend on WikiTree to get a count of profiles with the {{Unsourced}} template, and WikiTree+ (thank you, Aleš!) to get a count of profiles with the appropriate [[Category:Location,_Needs_More_Records]] category applied. But because both templates and categories are applied manually, there are a ton of profiles to which they should be applied, but haven't been yet. So that's why the tallied profiles show as nearly 40% "fully sourced", while all profiles show as nearly 100% "fully sourced". (This is one big reason why I keep saying that such-and-such a percentage of profiles on WikiTree is "supposedly" sourced.) As the appropriate [[Category:Location,_Needs_More_Records]] categories and the {{Unsourced}} template get applied to more McNair profiles where they're needed, both lines should get more visible. That might seem like going backwards, but it would actually be progress, because the numbers would more accurately reflect the state of McNair profiles. (Of course, sourcing those profiles which are unsourced or partially sourced, but aren't marked that way, would be better still, but even if you can't find any sources, marking the profiles appropriately would alert Sourcerers to profiles where their efforts are needed.)
