First ever golf gti... disaster
another option could be the engine has had water in it. giving you multiple sticking valves or even hydrolock.
those figure are well out of range. do as paul has said and give a full break down of how you did it please.

Well i think i did it right
Pulled the ignition leads, removed plug one and tested, replaced plug one and removed plug two and tested etc. Did i do it wrong, i had no one around to show me and the guides i've read and seen have all said different ways.
You need to disable the fuelling (take the fuse out of the fuel pump relay) and ignition (pull a wire off the coil) and do the compression test with the throttle wide open. Also, if all 4 plugs are out (except the one the compression tester is in), you'll get more consistent readings.

Does fueling make much difference Paul?

It prevents the engine inadvertently starting! (If the spark plugs were left in and ignition not disabled). If the ignition were disabled, spark plugs left in but the fuelling left, then it would flood and wash the bores, falsifying the results and contaminating the oil; if the spark plugs were taken out, you'd eject fuel/air mixture out of the spark plug holes when turining over the engine. If the plugs were taken out but the ignition system not disabled……..you get the idea.

I'll go and re test tomorrow, could it still be quite serious even though all cylinders are achieving some kind of compression?
Its hard to diagnose noises over the internet. Tapping & slowly losing power and then cutting out?
Could be something as simple as the dizzy has slipped, advanced more and more, then at idle the timing is sufficiently far out to not run properly.
Basically, if you have:
compression
timing
fuel (in right proportion, ie mixture is correct)
ignition
then the engine will run.

I'd say unless your dizzy is loose leave it alone, go back to the begining, check engine timing (check belt & tensioner too), ignition timing, then make sure all your carb stuff is correct, no sticking chokes, no damaged vacuum tubes, proper seals to manifolds etc….
Investigate where that tapping is coming from is it the cylinder/head, or is it something else.
And dont worry
