Sorry, I have only barely skimmed this thread, so it might have already been discussed, but I just wanted to note that @S_Alexander created another thread looking at how people’s ranks changed here:
Since both rating formula and ratings themselves changed, it’s interesting to see how ranks changed. I polled a bunch of active players. So linear.

Roughly like this, from linear fit 34k->23.8k
33k->22.9k
32k->22.1k
31k->21.2k
30k->20.9k
29k->19.8k
28k->18.9k
27k->18.2k
26k->17.5k
25k->16.7k
24k->15.9k
23k->15.3k
22k->14.4k
21k->13.8k
20k->13.1k
19k->12.3k
18k->11.7k
17k->10.7k
16k->10.1k
14k->8.6k
13k->7…
Here is another visualization and some observations
A few observations…
Old ranks from roughly 26 to 35 kyu have effectively been reinstated, but given a big boost to now be viewed as at least 25 kyu
The new TPK (20+ kyu) ranks were completely off the old scale
The adjustment slope of ~0.75 reduces the amount of handicap stones used. Two players that formerly played with 4 stones would now only use 3.
