I've read that the extra click supposed to act as trim on a double, but I couldn't quickly figure it out last night when I installed my ST-A410s on a 1050 series double drive train.
Instead the first click works for the small ring, the third click is perfect on the big ring (no rub across all 7 speeds), and the middle click just rubs the chain against the big ring, not enough to shift.
