I'm looking for some guidance or best practices on the situation where you've asked a question and already received one or more stellar answers.
On the one hand, as soon as one accepts an answer, the question is considered resolved. It's technically possible, but almost never observed in practice, to see a new answer to a "green" question (i.e. one with an accepted answer, which shows up green in the question feed). So you'd kinda like to delay accepting for a little while, not because you're expecting a better answer, just some new ones, offering different perspectives and data.
On the other hand, when someone posts an answer which not only answers the question, but does so in a comprehensive, detailed, well-researched and -cited, and often entertaining way, it's unlikely that any new answer will "supercede" it. So you know eventually you're going to accept it. And therefore witholding the tick seems kind of, I don't know, punitive? Or, if not that far, then impolite?
So it's a matter of a cut-off. After N hours / X days, etc, when does it start becoming discourteous to not accept a good answer? When do you, personally, start getting frustrated with an OP who hasn't accepted your (good, highly-voted, expert, etc etc) answer?
