I use 96% of the throttle (have a stopper under gas pedal)
I also leave the engine on for safety.
Changes should be done at (or close to) peak torgue point.
Use maximum torgue so if 5 gear is too long use 4 to stay on the torgue band. You dont want to fall under best torgue when accelerating. Fifth work best on my diesel with speeds from above 90 km/h, under maybe the best gear is 4, when using P&G. On diesels the acceleration should be as short as possible to see the best results.

I have also tried to push and glide in higher speeds with this technigue:
push to certain speed lets say 130 km/h. Then Glide gear on with slight gas on. I have founded that best results happen if you slow down at rate of 1km/h per 2s. So if you glide to 115 it will take about 30 seconds. I am not sure about results, because my scangauge works only with certain driving technigue where it is at the moment calibrated.
