Linescores: Scoring Runs Equal To The Inning Number

I look for lots of things in linescores, including teams that score an amount of runs equal to the inning of the game, i.e., one in the first, two in the second, three in the third, four in the fourth, etc.

I have no idea what the record is, but it has to be more than three, as that particular feat was accomplished on consecutive days this month.
