The point some folks are making is if you have one foot inside and one foot outside the shooting area while shooting, the rules say you are outside the shooting area. So, if you have one in and one out at the starting position, you are also outside the shooting area. The WSB said outside, so that requirement of the start position is met.
I agree with you to have the RM make the final call. After that, roll with it.
Fallacy!
Nothing is better than God
Banana is better than nothing.
Ergo, Banana is better than God.
