I think Ossoff is just over 17,000 votes in the lead and has a 0.39% gap in his favour. That should mean that he needs to extend his lead to just over 22,000 to ensure he has a 0.5% gap and the question of an automatic recount goes away. Even with the dregs of votes still to come in from mainly Democrat counties that target may still be achievable. I think there are also some 'overseas' votes (including the military) to add in to the totals by Friday. Even if there is a recount the likelihood is that the win will be confirmed within a day or two.
