I've had countless heads off in my time - and used to religiously check
the torque setting after a few hundred miles. And never once found it
needed it. I reckon they recommend that to catch ones which weren't
properly torqued in the first place.

How about all the other fixings in a car that get hot too? Should they all
be checked? If not what makes the wheel ones special? Especially since in
general they are vastly over engineered?

Right. That ruler was what the KF guy used first - then added a red
circular thingie. Which had no markings.

Maybe so - but do they check every single fixing on the car? The wheels
and tyres were an extra, though. Is that sort of thing dealer fitted? The
car wasn't stock - took 6 weeks to arrive.

It's a brand new car that hasn't had its first service. It's only 3 weeks
old.

When do they get the car back after delivery to check the wheel bolt
torque? There's not a 500 miles or whatever check anymore - and hasn't
been for ages.

Err, what are you talking about? Bolt torque or the puncture repair?

If you're referring to me it wasn't my car.
