There's no such thing as being pulled over by the police for being

the possibility of being caught by doing 36mph in a 30mph limited
section of road).

Of course you can be pulled over by the Police for doing only 1mph above
the posted limit. However, unless they are running a zero tolerance
campaign on speeding, which sometimes happens, you will not normally be
prosecuted for speeding as a result, if your only offence was speeding.

Indeed, the police (at least the North Wales Police who most
definitely aren't working hand in hand with the Welsh tourist board)
will quite happily annoy motorists who have touched the limit plus 10%
plus 2mph allowances as I discovered a decade or so back.

That is only a guideline, issued by the ACPO, for the point at which, if
speeding is the only offence, prosecution would not normally be
appropriate. It is not a guarantee that you won't be stopped or prosecuted.

Whilst, currently in law, there's no enforcable speed limit below
30mph and signage for 20mph and slower are merely 'advisory',...

I don't know where you get that idea from. There is a general relaxation
allowing an advisory 20mph limit to be associated with a flashing school
crossing signs without the need for a traffic order. However, any 20mph
speed limit or 20mph zone imposed by a traffic order is a statutory
limit and is fully enforceable under the Road Traffic Regulation Act
1984. There are also several vehicles which are limited by their type to
20mph or even 18mph under that Act.
