What about that rule?
If a WTA player is replaced by a LL AFTER the OOP has been posted this match will be cancelled, unless there is enough time (-- hours) for tipping players to replace their picks.
how many hours are "enough"?
This wasn't in the rules but it happened before that we didn't count a match because a manager forgot to include it in the OOP. It also happened that a match counted because somebody else noticed the missing match a couple of hours after the OOP was posted.
