I downshift like this. As soon as I put the clutch in I rev the motor and simultaneously move the gear lever for the downshift, so that the car is revving as I pass neutral. Shifting to the lower gear and then rev matching does nothing to relieve the wear on the synchro's, although it will lessen wear on the clutch, which can be very substantial when downshifting without rev matching.

Any time the car lurches when you release the clutch on a downshift, you are slipping the clutch and causing wear.

======================
Definitely a multi-tasking motion, using clutch, gas and shift as San Rensho explained, sort of all at the same time.
Anticipating the RPMs for the next gear is what I attempt to do. For my six speed, 1st, 2nd, 3rd are around 750-1000 RPMs apart. The higher gears are around 500. So trying to blip the RPMs (When clutch pedal gets pushed) up to were the next gear will run is the goal. You will see the RPM differences during normal up shifts. They're the same for down shifts. It not always down a consecutive gear either. It may be a couple or gears. Ex: 5th to 3rd, 4th to 2nd. Depends on how fast you had to slow down
