You cannot tell with one frame of Wiegamn alone, that's the problem Brian.
Stick with Altgens, you have a point but I would want to see it proven.
Two things to consider;
Lovelady is probably on the toes of his right foot.
He's also probably stood closer to the camera than we thought, not by the railing at all but halfway between it and the wall.
You don't need Dallas to prove this, just a set of steps with 7" risers. Go for it.
