I remember you've posted that spreadsheet before, good effort on your part.
As far as I remember we would need quite a lot of people to pull that off.

Out of the "main heroine 4" of the story, the one I like the most might be Di Yu (the first I got on Nutaku), though I'd be up to vote for Canola (the first I got on DMM ) too if we choose the 2*-4* category. I do have other girls I like in this range, but one step at a time I guess.
