I used to do a little drag racing myself. :0) Powershifting is keeping the throttle pedal on the floor, clutching and shifting as rapidly as possible. (if you miss the shift, you may be picking up expensive pieces).

Float shifting is a matter of RPM, road speed and timing. Float shifting is done with little or no throttle applied, and much more slowly.

Upshifting, depending on the engine, one must wait for the RPM to drop around 300 RPM. Downshifting is exactly the opposite. RPM must be increased by 300 RPM for each downshift (if road speed is constant). Generally you will be slowing during downshifting, so you'll only need to increase RPM by 100 or so.
