It gets complicated when you try too hard to make things perfect, ... it's a Mini :)
Did you find out if you have a 10 deg dizzy ? If so set timing so you have over 30 deg at 4000rpm but no more than 35.
If it pinks low down then you have the...
Sorry, the pic of that plug was from the guy AC DODD who you professed a dislike for. His day job is tuning SU carb'd engines.
I am going to be doing a bit more miles tomorrow going to that show so I will pull the plugs after that round trip...
100 thou. So 1/10 of an inch. Without measuring it, just looking at by eye on your pic, that looks to me a bit more than that.
Just saying. Have you actually measured it?
And I am not sure who you are referring to, is it you, being ironic about...

@Stanleysteamer well, well, well. Here is our SU carb "expert tuner" showing us all a perfect plug after a tuning session.
Just like the guy in the YT clip advised look at the fire mark/band on the earth strap of the plug. 100thou' band just...
Yes I know. If you wind the jet DOWN the mixture is enriched across the entire needle profile as the needle moves up and down.
Contouring the needle at the relevant "stations" affects the mixture at the station-specific rev-range.
The needle...
Just a thought, the jet in an SU isn't adjustable
All the jets are the same size and fixed in HIF 38 carb for instance, just have different needles for different cars
