If I may make a couple of suggestions?
1) I would add the word "usually" to the first sentence because otherwise it still seems too categorical.
2) I think we should define "plenty of warning" more concretely. My suggestion is that there has to be at least 10 hour window from the moment the manager posts the OOP and the early deadline. If it's less than 10 hours then we have to go by the official deadline. And also the manager has to note in big bold letters in the OOP that the deadline is different from the official one.
How does that sound?
Whatever we decide can we take a step back and make sure that a trend doesn't continue/start where the growth of rules and regulations for managers grows much faster than those for players? As evidence I'll submit the TT Code of Conduct which has more clauses relating to managers than players when it was originally proposed to curb behaviour of players.
No matter what the rules are people are going to complain and critique managers on these boards. There just always seems to be a group of people who can do so much better than existing managers, and a lot of the time the criticisms come from people who are too lazy to manage, read what the managers post, format their picks correctly, or all three. Managing a tournament like Indian Wells is A LOT of work and I feel that every time there an issue lately the complaints of players take precedence over the flexibility and understanding that should be part of a game where people with studies, jobs, and families are investing a lot of time managing this game so it can continue.
I support -Evita- in the need to clarify this rule but just want to make sure what ends up coming out of this discussion doesn't chain managers to their computers for a week
