Alot of your confusion concerning loss of control and/or escape is related to judgement of the official. Control is alot of times felt but not actually seen. In your examples 1,2, and 4, all are judgement calls. In the eye of that official he felt control was lost and in turn the escape was earned. As far as example 3, the bottom wrestler did not gain a neutral position as he had not turned and faced his opponent. The offensive wrestler still has advantage. If the defensive wrestler does not turn and face his opponent he should be called for stalling as he is not trying to improve his position. Again, alot of the rules in wrestling deal with the judgement. The more an official works matches, studies the rules and casebook, and attends clinics the easier the judgement becomes.
