I made a point of quoting the Mainichi because I was sceptical. But I'm also unsure about the Nihon Ki-in figures because they do include wins in women's and youth tournaments.

Can you give me the link for the Nihon Ki-in information on number of wins?
I'm one of the old generation. I read newspapers, magazines and books. The "link" is in e.g. Go World.
It's many years since I looked into the details of the promotion system, and it may have changed, but as I recall 1-dans get to 2-dan by winning 30 games. However, if no player gets thus promoted in that year, up to two players can get promoted by topping the prize money rankings for that grade. Since, by my reckoning no-one has any chance of getting 30 wins this year, and both Sumire and Terada have far more wins than anyone else. I therefore expect one or both to get promoted on prize-money terms on or around 1 January. Fukuoka Kotaro may be the fly in the ointment there because he's been active in the Chinese League B Division and did reasonably well. That may have bumped his earnings up enough. But, again, does prize money outside official NK events count?
Edit:
I decided to do a bit of online digging, which got me nowhere except for a statement that in 2019 Sumire's promotion-counting games record was 11-4. Since the Nihon Ki-in gave her official record for that year as 17-7 (i.e. including women's events etc) and the NK record for this year (2020) so far is 18-15, we can perhaps guess that her total wins for promotion in 2020 is about 12 or 13.
I tried going through the NK published monthly records but they are defective (no doubt CV played its part). My guess is that the Go World figures are compiled by the magazine and the figures that really count are compiled in the NK back office. But FWIW, I cam up with a total of 22 wins over the two years, with the possibility that a missing Ryusei game that I have and GW doesn't would make 23.
During the early part of this year she averaged about 5 or 6 games a month. So if she scores her usual 50% plus, she'll be 2-dan sometime in the first quarter of 2021 unless the prize-money rules supervene.
(A reminder that I listed the events that count for promotion in an earlier post in this thread.)
