Reasonable waiting period

[Otto von Blotto]

Good advise by all, take what you feel you deserve, if you spent an hour or so deliberating your turns agonising and planing every move then take the major, if you contempated through a few standard turns that took 20-30 mins to an hour of of your time and effort each turn go for a minor, or if you zap through the turns quickky or were playing a trusted and long time opponent take a draw or don't bother to register it at all.

As scud says it's not set in stone and results can always be changed if need be and your opponent agrees if he does bother to get intouch.;-)
