Hard to down shift

[Ulvetanna_imp]

The downside to dropping more than one gear at a time, is that the blip amount is different, so you need to coordinate that, and the muscle memory is harder to develop than if you drop just one gear each time and therefore need to blip the same amount for each gear change.

Not only that but every bike is different. I hardly ever use that technique on the street. The track is more predictable and RPMs much higher.
