The other thing to consider with pop reports for T206 and probably other sets is that more valuable/desirable cards are grade more often.
When I was really looking at a few groups pop reports what I saw was that for cards that should be equal, HOF players had about double the population of regular cards. That also worked to some extent for cards widely known for years to be tougher than the usual commons.
Lundgren Chicago is in that category. So I'd expect to see twice as many compared to the KC version. That the two are nearly equal makes me think that there are probably 2x as many KC as Chicago. That's complicated by the KC card being slightly tougher than regular commons.
For an extreme example, when I was doing that looking up I saw that there were more Magies graded than the Magee portrait. But it's obvious that doesn't come close to getting the comparable rarity correct.
