(sometime in Dec. 2022) To Yokosoo:
I haven't beaten it, either (am 8 off). Since you were asking for hints, I hereby leave you an invitation to Discord (forum), where you can talk to players. I hope you will find this and join us there. :)
Apologies to David, I couldn't think of any other way, how to give this INFO to yokosoo.
Invitation link to Discord (it will expire in 7 days):

EDIT, 13th Oct. 2023: I was 8 off, here, for a very loooong time. Was trying it, on and off, occassionally, but could never see better. Today was THE day. :D I finally saw what else I could try (which did not seem completely off, even before trying). And I came 2 off. It probably took me about 10 minutes more to find the last two steps.
GREAT Accelerator!
