Rotors allow for ~ 1mm of wear and after that are shot...and cannot be cut / machined under any circumstances per PAG.
It is NOT uncommon especially on track cars for an inner pad to wear more than outer. Porsche’s are a little less noticeable due to calipers having equal pistons on each side of rotor in most modern vehicles. That said, uneven wear w/in a pad is TYPICAL. Typical as in leading and outer edge as well as trailing tend to be chamfered relative to rest of pad. You will see evidence of such in wear markings on rotor and pad and degree of variance is relative to pad composition...I.e. it’ll be much more noticeable on OEM pads than track geared pads like PFC et al.
Good luck
