This board will pick up when the new Boxster book comes out. The people on PPBB aren't really tech people.

The clutch is manufactured out of similar components to your brake pads, and the operation / concept is very similar. When you're on the track, it's not uncommon for the pads to heat up and then lose a lot of their effectiveness. Well, the same thing can happen with clutch components. The clutch is designed to only be used a little bit at a time (low duty cycle). When you use it like that on a hill, it will heat up the disc, the pressure plate, and the flywheel, making it's effectiveness quite less.

Letting it cool off is a good thing, and it should return to normal operation when it's cool. I suppose it's possible to warp a flywheel much like you might warp brake discs when they are hot, but I haven't really heard of this happening.

Bottomline, this is normal, and would probably happen in any car. It's not good for the clutch, and it may be a clue that it's getting closer to it's end of life, but I wouldn't worry about it until it starts slipping under normal circumstances.
