I blip downshift to rev match the RPM's, assuming that save the clutch and wear and tear on the transmission. I don't really heel toe it, any advantage if your not on the track?

It first came up when the IMS failures weren't happening on the heavily tracked aggressively driven cars like you would expect, but on the ones that were babied. Turns out the variocams were designed to excel at high RPMs, which is why you feel the nice boost 3k+, but not so much at lower RPMs.
He suggested keep it under 3K when warming up, and upshifts should be done in the 4-6K range.

No, I cannot think of any advantage - other than the selfish pleasure it brings.

I started practicing rev matching downshifting about six months ago with my 330CI and 986 Boxster. I'm pretty good at it now but find the 996 harder. I find I have to depress the accelerator further than the other cars. Anyone else experience this?

Downshifting puts the braking/drag at the rear, helping to keep the car aligned with desired direction of travel in conditions that warrant.
Not especially needed with ABS....

Think of all the heat your brakes generate instead being transferred through your clutch and transmission. The only real case for compression braking is on steep downhill grades, and even then you should be rev matching your downshifts and just using the engine braking to hold speed.

Or not. These clutches are pretty solid and if done properly down shifting places no additional wear on the them than any other gear change. Riding the clutch or dropping the clutch is what shortens their lifespan.

Brakes are for slowing the car, transmissions are used to accelerate the car. Case closed.
