Out of the Frying Pan....

i noticed after reving high if i clutch-in quickly the pedal takes a moment to come back out. this does not happen on my G which uses the external slave cylinder.

i think the premature csc wear happens to those clutching-in too quickly after high rev.
even through the excitement, i think one needs to play it cool on the 370Z and go gentle during clutch-in even if one dumps it into the next gear going WOT.

OP i drive mine to DT toronto and back to the suburbs on frequent occasions. i've done it in sun, rain, hail and flurries. the only time i had problems was the first few drives in. was pretty hard. stalled maybe twice doing the DD. once on an uphill. once on a downhill. don't ask about the later one.

it's actually easily managable. i did find removing the helper spring made it a lot easier to tell. but is a very high on/off. my buddies don't believe me when i say i have like 1cm between engaged and full clutch and then about 6'' of travel to the bottom. lol they wouldn't know coming from civics/sti's.

interesting hypothesis on the csc wearing. i notice that the clutch plates shudder a bit when you're revving hard and push the pedal a bit too enthusiastically.

usually i'm just gentle.

This is because you have 2 totally different clutch designs between the 2 cars, The 370Z/G37 clutch is what causes these issues at high RPM, What you are feeling is the pressure plate "reversing" from centrifugal force. Just a bad design. This can be corrected to a point with proper clutch adjustment. If you are pushing the clutch slave too far because the adjustment is too far out it will make it worse.

The earlier 350Z/G35 clutch or a quality aftermarket doesn't have this issue.
Is has 0 to due with the slave design.
Jamming the pedal should not effect the slave either (unless it's a stock OEM unit that is getting ready to let go)
