alot depends on the actual make / type of clutch fitted, I fitted a cheap American paddle in my old SX200 and they recommended an extended running in period of around 500miles I did this and had no issues with even though it was handling over 350ftlbs of torque, I subsequently read about others who’d had issues with this particular type of clutch and to a man they hadn’t followed the running in advice, and consequently had problems handling less power and torque, some form on running in just to get all the friction surfaces mated up right as got to be good for the longevity, and as previously said gentle normal running with smooth gear changes and no hill starts etc is the best way, but as for how long you need to do this before giving it some stick I’m not sure so follow the advice of the manufacturer

The clutch is only engaged whilst changing gears, it has no other function otherwise, just dont do standing starts and dont slip it, you can drive at 6k rpm, just be gentle with the changes for a short while

Could be a newbie question here but
If thats the case why does a dodgy clutch slip in high revs? Isnt a clutch only disengaged when changing gears?
When i got my clutch done for the first 500 it didnt feel 'quite right' but after 1000 + it feels superb

Correct, the clutch is disengaged when the pedal is pressed which allows the shift. At all other times the clutch is engaged.

I guess it depends on how bad it is, maybe it does need 'some running in' to settle down and become smooth, this type of single plate, full segment organic clutch should have broadly similar driving characteristics so the OE, it's only when you get to multi plate or paddle clutches that you expect a certain amount of judder, tricky biting point and on /off feel etc,
I think all you can do is get some miles on it and hope it improves.
