As shifting up or down required gear speed matching. To day we use rev-matching to do the same thing. Simply pressing the accelerator with the clutch pressed before engaging the next gear will do the same in a modern trans. Rev matching is NOT double clutching.

Ultramaroon was 100% talking about double clutching, and the rev match was implied because lol 6 > 3 gear change. And I 100% agree with your post.
I typically double clutch my downshifts if I'm not in a hurry because the gearbox agrees with it very well. Without it there's a resistance, a hesitation of the synchros doing their job, very much a good thing, but when you nail the double clutch the gear lever literally falls into place as if you could blow it into gear like you're blowing out birthday candles. Oddly enough when I'm running around over 5k rpm on track the gearbox shows almost no hesitation, responds very willingly to roughness, but when I'm casually driving around town it seems to be much more responsive to the double clutch, you have to know how to drive your car in a way that makes you happy.
And sometimes such as with a cold gearbox second gear in this car is next to impossible to engage even with liberal amounts of gas pedal in neutral to get the transmission up to speed, there has been more than a few mornings when I give up and just coast hoping I don't have to bang it into gear and ease it back into first.
Honda released official info on the S2000 blaming several gearbox failures on skip shifting putting unnecessary load on the synchros, double clutching is absolutely viable in terms of prolonging the life of the gearbox.
Whether or not that's necessary will remain to be seen, we'll find out in 5-10 years time if any gearboxes are failing at the 60k-100k-200k mark. It absolutely falls into the category of personal preference at this point but it doesn't hurt to be aware of it.
