I plan to mentor this in GCI

@Ladsgroup: Could you provide more information for contributors? Which code base is this about, any documentation explaining how to change the "number of observations" for certain wikis? Thanks!

Okay, As an example of adding new observations you can see: https://github.com/wiki-ai/editquality/pull/48/files
In order to change it they just need to change the query in quarry: https://quarry.wmflabs.org/query/12494 and re-run the feature extraction, etc.

Copying @Phantom42's comment from the GCI site here:

"Just a bit of progress report: everything is okay. I successfully created SQL query and edited Makefile. Now I am generating new models, no problem too, but just need to wait a bit.
Actually, is it okay if the resulting number of observations will be slightly smaller than 100k? Because of network errors or something like that, the result will be around 99976. Is it okay? If not, I will try to restart."

It's okay to be less than 100K it happens due to deleted revision, or deleted parent revision, etc.

Task completed. Link to github pull request: https://github.com/wiki-ai/editquality/pull/53
If anything is wrong, please tell and I will fix it.
