A note I didn't cover in the video. You will see me generate an incorrect result at first. The note is "Where you click on the base and target objects makes a difference. So at first i clicked on the upper left corners and got a "sideways" flow. Before i changed too much I just re-did the flow and clicked at the center of the 2 objects. I think it is a "General area" calculation.
Anyway, this vid can get you fooling around with flow.
