It's all about the skills, Dave! 
I'm a dancin' machine!
Seriously, I agree that double-clutching is not necessary. All I can say is that it's marginally easier on the transmission -- we already know that the synchros in the S2000 '00 - '03 gearbox have been slighly suspect over time...

Double clutching or heel and toe is more about not upsetting the balance of a car when at the limit of traction setting up for a turn than it is about preserving the synchros. It probably is easier on the transmission even during normal driving, frankly, I never thought of that before.
But I don't understand the need to do both double clutch and heel & toe simultaneously. I though they were two different methods for accomplishing the same result.

Since we are on the subject I will throw out some advice from a Honda engineer (Woodward) on this topic:
" ... The transmission main shaft, no longer connected to the engine, is freewheeling in the transmission. Given enough time the main shaft will slow down but not as fast as the engine. "
Caution with Skipping Gears: A Honda engineer indicates the problem with skipping gears is the same as shifting from first to second very fast and making it grind. ...
The cause is driving the car high RPM in 1st, shift into 2nd, then high rpm into 3rd. At this time the engine is screaming it's song and the driver usually feels the need to bring the engine RPM down so he (she) shifts into 6th gear and drops the RPM 3 or 4,000. The problem is that 6th gear synchro isn't made to work that hard. (What is 5 to 6 RPM change? About 800 RPM?).
