I think you mite be better off sticking new plates in now if you have been using them since the start of the session with the races you’ve done and all the practise/trackdays. The plates have probably had it. If it has been working fine then plates it is.
I would change them now for your racing and keep the ones you’ve got as spares.
I know that’s not the most cost effective way but you can’t go out at Donnie with a slipping clutch,
I think you have to have a fiction plate at the back of the clutch to build off, or is that just the dry ones
