I did a quick tally because I thought it was ~51k. Biden would have to net ~14.8k (I’ll say ~15k) votes, which of ~51k possible means he’d have to win ~33/51k. Basically ~64%, ~2:1 Biden ratio.

If it’s ~48k possible, that means ~31.5/48k, still ~65%, ~2:1 Biden ratio.

Spez: of the remaining (per https://twitter.com/costareports/status/1324359180329930752) here is the current split (per https://results.decisiondeskhq.com/2020/general/georgia):

61k votes are outstanding in Georgia (I don't think it's 61k, closer to 49-51k, the math doesn't add up to 61k if you add each remaining county's remaining votes). If current splits hold up (NOT accounting for if the mail ballots were election day or earlier, simply taking the averages per county for all types of votes):

17,157 from Chatham (LEANS BLUE) (Biden 57.66% / Trump 40.97%) = Biden 9892 / Trump 7029

+

11,200 from Fulton (LEANS BLUE) (Biden 72.56% / Trump 26.28%) = Biden 8126 / Trump 2943

+

7,338 from Gwinnett (LEANS BLUE) (Biden 58.26% / Trump 40.41%) = Biden 4275 / Trump 2965

+

4,713 from Forsyth (LEANS RED) (Biden 31.96% / Trump 66.55%) = Biden 1506 / Trump 3136

+

3,641 from Harris (LEANS RED) (Biden 22.23% / Trump 76.72%) = Biden 809 / Trump 2793

+

1,797 from Laurens (LEANS RED) (Biden 35.18% / Trump 64.10%) = Biden 632 / Trump 1151

+

1,552 from Putnam (LEANS RED) (Biden 28.59% / Trump 70.49%) = Biden 443 / Trump 1094

+

1,202 from Sumter (LEANS BLUE) (Biden 52.03% / Trump 47.14%) = Biden 625 / Trump 566

+

700 from Cobb (LEANS BLUE) (Biden 56.33% / Trump 42.04%) = Biden 394 / Trump 294

+

= Biden 26,702 / Trump 21,971 = BIDEN NETS 6,000 (BIDEN NEEDS 14,800)

Oofff....

It'll be enough to flip it to Biden and them to "claim victory".
