I would say that Lead & Follow has to be performed as close

The issue I have is that I'm doing this in wave not thermal.
I want to leave the guys in lift and go off to check the next bit

good, actually is, before I call the guys to jump into it.

On recent flights around here (Scotland) I've come back to the

4 hours later and the wave is still running. So there are less

The issue here is that the terrain is generally unlandable.
The Sink can be horrific.
And we are usually operating in winds stronger than 50kts at
cruising

None of these things are familiar to the guys asking for the lead

follow.

We fly in conditions such as you describe in Northern NH & Maine
US.

Pair / team flying tactics are very useful for figuring out the wave,
but

A mile

You do not need to be in visual contact to pass useful information

Use of any sort of GPS device including tracking is made difficult

Happy to pair fly in such conditions. The other guy has to be

I think Roy's newbies are 1000hr pilots looking for a diamond height
As I have been doing the same thing at Denbigh I know how they
feel.
You are 12000ft ,on O2 above 7/8 cloud looking for the next good
lift, the LX is giving all sorts of winds because its not good if you are
not circling, all you can do is keep your eyes on the remaining gap
in the cloud and your moving map.And voices on the radio say
"I've got 6Kn 8K out at 160 degrees from base"
and you think " I am not going there I won't be able to see my hole
in the cloud"
So next time you ask a local like Roy if you can follow, which puts
pressure on him that he doesn't need.
There are some good answers on u.r.a.s.b about flarm team
settings
that I am going to try on my next expedition to the Welsh diamond
mine.
