If you skip gears, you have a larger disparity in input and output shaft speeds, and that burden is put on the synchro to overcome (additional wear). So by sequentially rather than skip shifting, you make the synchro's work easier.

You can safely skip shift if you double clutch. By double clutching, you manually match input and output shaft speeds and negate the need for a synchro. This is how guys who killed their synchros continued driving and how EVERYONE drove before a synchromesh gearbox.

The beauty of SRM is that it allows a perfect 6-4 double clutch downshift and even does the blip for you.
