Well thank you Stan Evil - you have answered my query.
I just cannot believe that you can be adjudged profficient to fly a twin and find your licence invalid for a single.
Is it just me..............but I frankly don't see the logic.
I wasn't suggesting the need to fly 12 hours in a multi - but had
mistakenly concluded that perhaps if you did, it would cover the single requirement(test or no test).
Life with a PPL never used to be this complex
