I wonder if the UWW could adopt a policy of something like the following to prevent guys from running at the end of the match, something that almost everyone does, including the very elite guys:
With one minute left, if you are evading action, you get a warning (like a raised fist in folkstyle). If you continue to evade (run), the other guy gets a point. This way, you are warned and have the opportunity to engage and change your action and it doesn't leave things immediately in the hands of a ref.
It would be a policy in addition to the caution plus one when guys go out of bound with larger leads. And it would help to rectify evasion when the score is much closer at the end.
Just a thought.
