I don't look at the Ding line.
I look ahead of the Ding line at where the swing meter will be when I need to click the mouse so the hit is on the Ding line.
At least when I want the hit to be on the Ding.
I usually aim putts inside 10 feet by purposely missing the ding - late for a right to left break, early for a left to right break.
