Hmm...
OK I had the clutch done, finally, 8 days late

Right now it's just starting to bed in - twas sharper than a katana for the first 20 miles, with a bite exactly 2/3 the way up and covering about a millimetre from full-off to full-on... bit like being a learner again!
The gearchange is MUCH improved. Everything is a lot smoother with the pedal down (even reverse is like silk if you give things a second to spin-down), and a lot more solid with it up (accidentally spinning the tyres on one-third throttle, chirping them in 2nd in the rain - previously it was reminiscent of an automatic...). Crunches a little on 1st from time to time when going from 2nd, but the synchro's probably knackered with everything that's happened, and I can work around it easily.

Just waiting for the bite to soften a *little* and it'll be perfect. As it is, I've got the launches sorted, but between 2nd 3rd 4th its still jerky

Just hope it's another 25,000 before it gets as wooly and full-pedal-range as it was before, because it was £185
PLUS TAX ... (add pre-tax charges of 25 for the blowing exhaust, 29 for a new 155/70 tyre, 40 for a new front wheel bearing, 30 to get the seat re-welded as the runner was actually coming away from the floor...... adds up to "ouch" - hope i get the gearbox money back) !!!!
Wish i'd flogged it off to some desperate, newbie driver student and spent the difference on getting a 1.3 now.... but i only thought to get a quote for the clutch
With the exhaust fixed and the bearing silenced, i'm prepared to forgo the 5th gear as everything's a lot quieter... it still gets distinctly and quickly more buzzy past 63mph, but hey.... the overall noise level is lower, so screw it

... the car just glides along at 35, beautiful, and the seat's comfy again.
Anyhow, he showed me the clutch plate that came out, and basically it was down to the rivets in a couple places, he was impressed I was still able to get about with it in such a state. Also explains my particular symptoms - it would slip much of the time, but occasionally I guess the plate got some purchase on an exposed bolt and pulled a little more forcefully (and refused to disengage properly).
Yours I suspect is something different - it depends what you mean by the bite point. Do you mean "where the car starts to inch forwards" or "where the clutch is no longer slipping at all" ?? The first should be fairly close to the floor but give you a good inch or so of travel where it's not giving any friction at all (I had about a NEGATIVE half inch of travel

would only have disengaged totally if i'd cut a hole in the firewall so I could push the pedal further), and ditto for the top end for the fully-engaged point (same again - it simply couldn't grab hard enough).
Take a peek at your cable, see if it's self adjusting (capped-off end) or manual (two nuts). If it's auto, pump it a few times and see what happens. If it's still crap, invest the time and money in a manual replacement (seeing as VW themselves dropped the auto type in the mid 90s as it's rubbish).
If it's manual, play with it and see where the bite point goes
I think clockwise, when you're facing towards the rear, takes it closer to the floor, so you may want to move it anticlockwise and see if that improves matters any. It's possibly a case that it's adjusted so close to the floor that when cold, it's just-about disengaging completely and feels ok, but once everything warms up... the cable expands a little... can't pull the actuator quite so far as a result... and when you have the pedal to the floor it's not anymore disengaging enough for a smooth gearchange.
Good luck
