Sorry for the delay.

Most of the results can be found in the mail Calculating interlinks between Wikipedias that was sent to the analytics group.

@Amire80, can I resolve the task?

I asked editors on the Hebrew village pump about their editing methods. Got some interesting answers and leads. For now, they are summarized together with other conclusions here: https://docs.google.com/document/d/1StzyGdf6rOs669wt0Al_8Tx7Ml0KwFCdw5f9t_AWvnY.
I plan to open a page for the conclusions in the project page later this week.

• By working with the Hebrew Wikipedia dumps, I can get a list of the Hebrew Page IDs (and if wanted - the titles) that have a corresponding page in English.
• It seems that we should try to work with wikidata as the information there is solid.
• Therefore, I tried to understand what Magnus is doing in "not-in-the-other-language" tool but right now, I can't find the script (his repository is a mess). I will try to contact him and ask for more information as I think understanding how this tool works might help us in the future.
