Please do not take things out of context, I said, PTFE does not prevent leaks, a correctly made joint prevents leaks, you do NOT need PTFE on a compression joint to make a seal.
Yep you shouldn't use PTFE on compression fittings
That's what plumbers mait is for

And your blind prejudice for arguing for it, even after I have proved that the best known manufacturers of compression fittings in the UK say it should NOT be used, take your argument up with the manufacturers, I am stating facts from the manufacturers, if you are saying they are wrong take it up with them
I argue in favour of it because I have tried the method, it is simple, cheap, and it works by preventing leaks on compression fittings. That is not blind prejudice. It evidence-based fact.
If there was a reason like "it makes the pipe split" "it causes a fire" "it makes the brass dezincify" "it blocks venting in the case of overheat" I would listen to it attentively, and examine the evidence.
Have you tried the method and found something wrong with it?

I don't need to try it, I follow the manufacturers recommendations and it works perfectly well and it is cheaper than your method as I do not have the additional cost of the PTFE.
If you bothered to read the email replies I had from the manufacturers in the topic PTFE on compression fittings, you would see the line "The use of these on a compression fitting not only could create a false seal on the pipe work causing a leak, but would invalidate the warranty we offer with the product as it is not installed to our guidelines". so may reason is the guideline of the manufacturers.
On new copper/fitting the PTFE makes it more difficult to feel the desired tightness on the spanner (eg. I can't always tell if it's under or over done, hence use pastes). However if having to re-make an old compression on a zone valve, cylinder connection, rad valve etc. or where old olive/pipe mis-shapen, The tape does help.
you mean you never ever ever get a leak from a compression fitting?
That's perfect.
The rest of us do.
I have looked at the joints I made two and a half years ago, with PTFE, and none of them has any sign of weeping, limescale, or green runs. I didn't become a better plumber two and a half years ago, I just started using PTFE. The cost and time of re-making a leak would be vastly greater than the cost and time of using PTFE.
OK, thanks for that, though as an amateur I haven't got such experience of touch and feel
I rely on strength of wrist and an appropriately-sized spanner. Maybe I do mine a bit too tight?

I ALWAYS use jet blue or sometimes ptfe on comp fittings,never had a problem
If you're covering just the olive, it's unlikely you'll have any trouble. 100% of the compression/PTFE leaks I repair are where the DIYer (or incompetent plumber) has taped the thread and not the olive.
Leaks on compression are caused by over tighteneing or not tight enough, there is an art to knowing how tight they need to be.
the manufacturers state not to use PTFE as they say it will cause leaks.
