This is excellent IMO. Another benefit from placing a via point just after a turn is that your direction arrow will begin pointing toward it as you get closer, yet another indication for you that something is coming up to be aware of.
Also, via points at intersections tend to be ones that you are going very slow at. Slower speed means a much smaller tolerance for 'hitting' the spot. Just past the intersection usually means you are rolling along again and you'll 'hit the spot' almost every time.
Good info here.
