Where do you shift your R56?

I don't drag race, but I am trying to go quick. It depends on the R56 and the gear. The theoretical way to do it is with a torque curve and you have to work out when the added gearing of changing up is less of a disadvantage than falling off the other end of the torque curve.
I have a spreadsheet to do that, and there's also an iPhone ap for it.
In a Cooper, its always advantagous to change up at red line.
In an 08 Cooper-S, red line from first and second, and slightly under redline for the higher gears.
In a 2012 JCW, its red line from first and slightly less with each gear, but the time you change up from 4th its 5900.

On my stock 2006 R53 I would normally shift at around 5500 RPM, this would leave me at about 4500 for the next gear.
If I shifted closer to red line then the next gear would begin around 5500, and the butt-dyno felt like there was less pull starting a gear that high.
So far my R59 feels about the same, but to be honest I haven't pushed this car as hard as the R53.
Each car is different, a little experimentation is needed to figure out what works best for your car.
