It's called "double-declutching" !

Even on a modern car it will make gear changing up or down the gearbox quicker and smoother, if you can do it properly, also it will not do any damage to the clutch or gearbox and it will save wear on the synchromesh.

It can be done in under a second.

To change up a gear........ off acc, dip clutch, gear in neutral, off clutch, dipp clutch, engage higher gear,release clutch, acc

To change down a acc, dip clutch, gear in neutral, off clutch, rev up on the acc, dip clutch, engage lower gear, off clutch.

In normal gear changing the synchromesh matches the revs of the engine with revs of the gearbox, with double declutching you match the revs of the engine with the gearbox, and it works quicker than waiting for the synchro to do it.

A problem well stated is a problem half solved !
