If you have to go through this procedure, and it actually works, you now know your throttle valve is probably dirty, wouldn't it be a good idea at this point to just disassemble and clean the throttle body and valve, then reset the ECU?

Good observation - I was thinking of this as well, so I pulled out the intake tubing and inspected TB before doing the procedure. It was reporting around 2.3gram/sec loss the last time, and I wanted to see if cleaning the TB would further reduce the flow loss.
However my TB was basically spotless apart from the dye markings and a very light layer of dust, though I suppose there would always be some form of compensation made out for differences/variations.
There probably isn't any perceptible performance loss either - given that at around WOT the engine is taking in 143g/s, a 2.3g/s loss is slightly less than 2% which is negligible when calculated by the ECU as a load.
