The votes are coming in much more slowly now, but for a few states I've been watching it looks like the current and final majorities (deficit in North Carolina) for Biden will be:
Georgia current majority 14,149, additional 40% of remaining 3,000 votes brings final majority to ~15,350 (<0.5%)
Arizona current majority 12,813, reduction of 13% of remaining 53,800 votes brings final majority to ~5,800
Pennsylvania current majority 45,516, additional 49% of remaining 136,300 votes brings final majority to ~112,000 (>0.5%)
North Carolina current deficit 74,870, additional 27% of remaining 104,800 votes brings final deficit to ~47,000
Nevada current majority 36,726, additional 21% of remaining 120,900 votes brings final majority to ~62,000
All calculations somewhat simplistic and with some inaccuracies. Additional votes based on performance in the state from votes recorded since 5/11/2020, "additional 40%" means that Biden is leading 70% to 30% in these, and hence the difference accounts for the increased majority.
Mail-in and other votes counted in North Carolina over the last few days favour Biden, but not enough to overcome the lead already established by Trump from voting on the day. Conversely, in Arizona the most recent votes counted go in Trump's favour, but not enough to overtake Biden's lead there.
