If you are shifting 'UP' (say from 1st gear to 2nd gear) you don't need to blip the throttle. Especially if the clutch pedal is still pressed in as blipping the throttle with the clutch pedal pressed down will have no effect on the speed of the gears in the transmission.
If you are shifting 'DOWN' (say from 3rd gear to 2nd gear) then it may be helpful to shift into neutral - release the clutch, blip the throttle, press the clutch and then complete the shift into the lower gear.
The whole purpose of the 'double clutch' is to match the revs of the gears when you move the shift lever to the next position. When you are shifting 'up', the gears need to slow down to match the next speed. They'll do this by themselves as long as you don't slam the shift lever from one gear to the next - just pause briefly in neutral between shifts to allow the gears to slow down.
During a downshift, if the car hasn't slowed sufficiently (I'm assuming you are braking & slowing down) then you might need to blip the throttle in neutral to speed up the gears and lighten the load on the synchronizers.

I have tried this method, but find that the aforementioned method works well as well on the downshift unless I am trying to make 'er engage greater than 4k on the tacho, then your method works better...
am I in the possession of a possessed auto?

A blip with the clutch pushed in does help as it breaks lose the clutch.
even on a good clutch there is some drag. The most when it is at the same speed as the clamp.
but once is is spinning vs the clamp it is free and the drag is more or less gone. I think you might even get a air cushin.
