^ Dont u mean, as u r traveling along in gear and want to downshift, you dip clutch, put into neutral, release clutch, blip throttle to rev match, dip clutch, put into lower gear then release clutch. It should slip into gear easier than before, even if you do have a modern car. But as has been said, its pretty pointless.
However rev matching and heel and toeing on the downshift is a very benificial thing to do as it will prolong the lefe of youe clutch, drivetrain etc.
