Some explanation...
I guess you kinda have to think about it, but if you plot the effective gear ratio, you're going to see six values for being in-gear, and outliers between gears. So just look at the vertical axis, and you get the 6 constants for the gear ratios. This is just a number that you multiply by rpm to get a speed. Could just as well be presented as a set of sloped lines.
Plotting the rpm on the horizontal giving what revs are used for each gear, shows (bottom-left area) where the car transitions from not moving to moving, so you could plot launch-control effectiveness. There's a few lines towards the right near the bottom of the chart where the clutch was slipping a bit more than it probably should, which is a piss-poor getaway.
Also, taken as logged data, especially on a manual, you could pull out how long on average you take to shift, so if you wanted to improve on auto-x or racing, you'd look at shift time, shift revs etc.
I'm planning a Torque add-in, and this is just a sketch of the kind of info. Clearly still needs some work, as always...
As an example, look at the third line up, third gear. Look at the right end. That's high rpms. Now follow the line left until you drop down, that's the DSG shifting down to second at the lower rev limit for third...
