Useful addition IMHO
As said, with patience and a lot of care you can achieve the required precision with the pots from the BOM - I just did it, so it works.
But it would probably be more precise / quicker (depending on level of the builder) with multi turns.
Good that thanks to you people have now the choice.
If I build a third one for a friend I might well give those multi turns a try and then report here so I can share my experience between the options.
The least I could do for such a great community...

I can't verify the pin layout against everything, but I can report success with Bourns 3339 series trimmers (4-turn) in a few things. Example linked below.
https://www.mouser.com/ProductDetail/Bourns/3339P-1-502LF?qs=pSi0RBzb0orX5sCUZr39lQ==
They're more expensive that most of the 25-turn trimmers, and they may not work for every board, but there are lots of things between single-turn and 25-turn available.
So, I have no idea if they have the 'hysteresis' / spring 'issues' sometimes associated with 25-turn trimmers or if they offer all the benefits of single-turns, but to me... they were a nice compromise.
May be worth a look.
