im talking about a sequential transmission thats completly mechanical. you use a clutch to move off in first gear and then the clutch is no longer used. there is a ratcheting drum, and when you press a lever one way it rachets and moves the the next gear up, and visa versa. this is the type of transmission used in motorcycles and race cars and etc. there is no use for a clutch to double clutch after 1st gear. watch videos of older 70s and 80s car races and see double clutching.

Ok. Even if you are talking about a mechanical sequential, they still don't wait for the revs to drop and then shift. It just takes too much time to double clutch or wait for the revs to drop when racing. I think the 80's were too modern for double clutching, maybe the 70's too, but i could be wrong, but my dad did have a 73 Capri that he didn't have to double clutch and that was just a street car. The older cars that had to double clutch didn't lose time realtive to other racers because everyone had to do it. Now a days where double clutching is a not required, you will lose time in a race to someone that is not doulble clutching.
