Update:
I confirmed the "over 10 IBU keeps lacto in check" rule. My lacto culture did almost nothing to my sour wort BW. It has had a month and a half to work on it and there is only the faintest hint of sour. I'm going to add lactic acid at kegging to compensate, but I won't be making that mistake again.
