I will come clean and state I got my full A1 license through taking a DAS course. I did however ride scooters in my youth (so wasn't unfamiliar to motorcycles).
At no time did any of the Instructors through the "big bike" lessons, talk about blipping the throttle for smoother (+ mechanical wear reducing) gear changes.
It's down as an advanced technique, primarily Sports bikes (on the race circuit), when decelerating rapidly, from high speeds, is a norm.
In which case, why should it be necessary to "blip shift" under normal, public road riding/commuting circumstances?
If you have physically slowed to the point you feel a gear down (or 2) is necessary, the engine has already slowed sufficiently, and the gear down wont affect the revs to any great extent. Hence a "regular" clutch in / change gear / SMOOTH clutch out, should be sufficient?
..............perhaps I just don't ride fast enough
