Missing eras in tournament data

With the announcement of Validation data - 2 it was mentioned that test eras 854-899 were being replaced by val eras 197-206. However in the downloaded tournament data file test eras 853 and 900 are not present. Am I missing something here?

This is just a difference between the time it was announced vs the implementation by the time I finished testing and launched, you’re not missing anything
