I've recently created a new page listing every entry in my database for completions of OT VIII - the highest level in Scientology.
You can see the list of OT VIIIs at https://www.truthaboutscientology.com/stats-ot-viii-completions .
This list should update automatically whenever new OT VIII entries are added to the database.
You can download the list to your own computer by clicking the CSV icon at the bottom of the page.
