With all due respect, Monty did not make a minor (and probably legal, if murky) improvement in the character of his lie he made a major (and definitely illegal) improvement in the position of the lie itself, which significantly affected his STANCE!
Pre-rain delay he was unable to find a comfortable stance as his ball was so close to a bunker. Apres-rain delay his ball was placed so much further away from the bunker that he had a normal and comfortable stance.
Please do not try to tell us that a professional such as Monty, with so much on the line, would not have known EXACTLY where his ball was in relation to the bunker, nor that he would not have spent a lot of time over the night thinking about how he was going to take a stance and play that shot once play had resumed the next day?
Monty knew exactly what he was doing, even if he might have repressed that knowledge to suit his purposes(narcissism).
He cheated, and should have "returned" his ranking points as well as his prize money.
