The GT6 implementation shows us two numbers on the horizontal axis. Zero and another one. Is this the over-rev cutout? It should be clear.

It also shows us the values of the maximum power and torque, however, this adds nothing since both these numbers are in the table above.

There are some vertical grid lines, but their position is not quantified. For example, I'm looking at a Jag with rpm going from 0 to 7,300. In between these values there are 6 vertical grid lines. Clearly, they do not mark the thousands of RPMs. They just seem to be arbitrarily placed. If I look at the same chart for the LCC Rocket, it has the same 6 grid lines, however the RPMs go from 0 to 13,500.

There is never an indication of the actual RPMs associated with points on the torque or power curves. Such as the peak. Or the range of RPMs over which the torque or power exceeds some percentage of the peak.

What I'm looking for is some actual measures upon which to base my gearing choices.

To date, I've just been working on trial and error based on guessed interpretation of the charts.

A blown up version of the chart with labelled grid lines would be helpful.
 
Yes this bug's me also.
In GT5 it used to tell you max power@what revs and max torque@what revs. And these used to change depending what modifications were carried out to the car. This used to be ideal for gear shifting.
Now with the lines, like you say, it's all guess work.

Why change this? It's simplification where it's not required (or useful). One step forward and two steps back. Again.
