It came from a long discussion about double-clutching. I didn't "get" double-clutching until I realized that there are THREE pieces of spinning metal, not two.

Double-clutching reduces shock at the 2 3 boundary. Releasing the clutch during the double-clutch manuever prevents the 2 from spinning down and causing shock on the 2 3 lock. Rev-matching alone only reduces shock at the 1 2 boundary. This also explains why sychros, which absorb the 2 3 shock, make double-clutching obsolete.

At least, that's how I understand it! Could be wrong! Transmissions are mystical things!
