I’m not aware of an update official concordance table. Do you have a link?
In the past, the organizations rarely issued updates - typically when there were fundamental changes to one of tests.
I pay no attention to data like this in “blogs”. Try a search sometime for “colleges with highest SAT scores” and compare them to actually data from colleges. The data is simple to obtain and the variations are laughable. Caltech’s average SAT is 1530, 1540, 1560, or 1570. And 3 schools have 75th percentiles of 1600.
I’d post the links those with consistently bad data, but CC always discards posts with the URL (they advertise here).
What tables are you looking at?
And fwiw, no one should be “worried” about a 1520.
