I have completed translation structure optimisations for the Calc function wiki articles, which were marked for translation prematurely in 2020. The articles in question were the mathematical functions and a couple of database functions. The work was coordinated with Steve Fanning, who let me know when the articles had been reviewed for content correctness.
This means that all translatable Calc function articles are now safe to translate!
You can find them by searching for 'Calc Functions' on this page:

The full list of Calc function articles is here: https://wiki.documentfoundation.org/Documentation/Calc_Functions/List_of_Functions
Numerous painstaking optimisations were made to minimise the amount of work for translators.
I will continue making reviewed articles translatable (currently 142 in the todo-list).
