ECT-Power is only useful for on/off and part-throttle type driving. For a floor-it drag race it's slower than normal.

Very good description. Good job. I would however refrain from saying that they are not very useful. In fact for 95% of owners they are very useful as it allows you to control the gears without worrying about stalling or over revving. In fact if you learn to work with the computer it can be very useful.

M mode in an IS-F... or a true manual... let you control the gears.
The ISx50 paddles?
It lets you set the maximum gear. That's it.

However, I only wish you would see the way I see on how to "use" these paddle shifters.
All your points are very valid on the point that these are not true gear shifters, but then does it matter how you get to the desired gear? It does get the work done, which is to downshift as needed by limiting the upper gear.
As far as up-shifting, the transmission computer does a great job of determining when to shift based upon the throttle position (fully opened WOT, half throttle, fully closed) and speed, which in essence communicates the drivers intent on how he/she wants the car to be driven.

Yeah hitting the REV limiter you will be fine, If my car is running great still with 73K & 6 track days & hitting the rev limiter almost every time at least once every session trying to hit that perfect "shift" say you will be fine. Yea wish our cars shifted like the F.

ha ha.... it is like the Matrix movie. yes it is mind boggling at first, but very simple to understand once you get it.
Key points / Definitive guide to using the Paddles:
Straight line acceleration: keep the car in 'D' mode. Do not switch on Power mode.
Quick boost for overtaking at higher speeds: Slap the gear stick to 'S'. Switches the gear to '4' right away. At the same time, hit the gas pedal. The rpm match that happens as a result of this is just wonderful and you shoot away like a bullet without any herky-jerking gear shift experience.
Rapid Deceleration for a sharp turn: Slap the gear stick to 'S'. Switches the gear to '4' right away. If you need more engine braking, slap the '-' paddle once or twice to get to '3' or '2' depending upon your need.
Maintaining power levels on a hilly road: Slap the gear stick to 'S' and slap the '-' paddle once or twice to get to '3' or '2' depending upon your need. This will keep your gear shifts optimized for the hilly terrain.
Not recommended: upshifting by means of the paddle shifters...neeee...gear limiters. Keep it in 'D'. The computer is optimized to shift very well for the engine and transmission combination and in my opinion bests most manual stick shift gear changes.
