skipping gears when accelerating

[BHML]

On a manual box, if you match the revs to the road speed, presumably going from 1st to 3rd or from 4th to 6th wont damage the gearbox, is that correct?

Don't have to match the revs. Change gear as you would if you wern't block changing.

With modern gearboxes, you don't even need to match revs really. A decent modern manual gearbox should last well beyond the car's economical lifetime.

I see, thanks... presumably with sequential gearboxes (e.g., DSG) you can't block change? i.e., can you go into second for just a fraction of a second before changing to 3rd?

Things like DSGs are pretty quick at block changing, although not quite instant. You just hit the button twice and the computer changes as fast as it can, which is a fraction of a second per change.

the good ones will go up and down the box as fast as you can press the flaps

A DSG box is two manual boxes sat next to each other in effect - so one box does 1,3,5 and the other does 2,4,6. Block shifting between two gears in the same half of the box will work like a normal shift in a manual box, so a DSG box changes down sequentially; at least the last one I drove did (although that was 4 years ago).
