I noticed, interestingly enough, at 15k an increase of 33% to 20k would hardly register and that a 30k would hardly increase my rankings as compared to a 40k which would really make a difference. From this I'd draw the hasty conclusion that 30k isn't really that big a deal and that 40k is something of a threshold to make a real attainment.
Yeah, for the Histographic category, only rank matters directly, not the score of the game. So, you would have the same rank and thus the same Histo rating with a Large Monarch game with a score of 17,100, 15,208, or 13,800. As you said, getting to 20k is almost nothing. However, if you could get a Histo game with a score of 30,001 somehow, you would jump to rank 25th. This would give you a histo rating of:
9*(25-1)/(73-1)+1 = 4.00
That would give you a QM rating of (4+1.5+1.4+1.25)/4 = 2.03
If you were to improve your other ratings all to 1.00, then your QM rating would be (5.25+3)/4 = 2.06
It seems that getting a Histographic game that scores 30k or more, you could improve your QM rating more than having all #1 spots. And you would jump me and Bartleby (though I might be improving my rating a bit by next update

).
True, 40k is a MUCH bigger jump, especially rank-wise:
Histo: 9*(14-1)/(73-1)+1 = 2.63
QM rating: (2.63+1.5+1.4+1.25)/4 = 1.69
That would get you up to where Tone is now, meaning that you would jump from 10th in the QM challenge to T-5th in the QM challenge.
