Now that July, August and September 2020 approvals are receiving their invitations almost at the same time, the model I prepared in September is ready for retirement.
However, the data in it may be useful for some future models and I am posting those here for the convenience of another data analyst.
Incidentally, I have not been considering dates on which invitations are received, only the approval dates and the dates printed on the letters. Therefore, if someone sees the value in researching the delays between the print and the arrival dates of invites, the good news is that they can search for that extra info by the members' usernames, in this thread, as well as in various naturalisation timelines' threads.
Good luck to everyone still on their journey to citizenship and to those who have already reached their destination, welcome to the club UK, it is a privilege to have you all here
