If one is to use impact hands location for an aiming point, does one mentally construct a straight line from the top or end of the BS to the impact hands location, and 'slide' the hands on the inclined plane on that line, while looking at the impact hands location?
At impact fix, my right forearm is pointing at the plane line WAY out to the left, around 4-5 feet to the left of my left foot. Thus using the point along the plane line where my right forearm points at impact fix is not practical.
