If the rule of zero tolerance is applied, that is the result. So a player can be present but if not seated at the board for the start of the game, they will be defaulted and the game not rated.David Sedgwick wrote: I don't see why you want to change things.

It would not be a legal draw offer if made before making a move, but the interpretation is still that illegal offers can be accepted.
In a match context a game agreed drawn without play is equivalent to one double defaulted. In a league context , the tie-break might be board points and it could then matter whether a game was counted as a mutual half point bye or a double default. Neither of these would be graded so if special circumstances are not reported, the league controller and grader have no (official) knowledge of the circumstances.
