Slipper clutch plate life?????

[Crackerr]

I installed a Ducati performance slipper clutch and Yoyodyne stintered clutch plates.
The clutch is wicked fun now and has increased my corner speed a nice amount!!!
Couple things I wondered about:
What should I expect for clutch plate life compared to the stock setup?
How often should the master cylinder fluid be changed, it's pretty black after two months and 2000 km
thanks in advance

I also have a DP slipper clutch, and if I had to guesstimate I would have to say it will last about 85% of a non slipper clutch, as the clutch has to slip both ways, so will wear a little faster.
I change my fluid when it becomes fairly dark. Aloha Alex

Thanks Alex, thats better than what I was expecting for plate life.
Fluid gets changed next week.
