Can I get a bit more information on this?

According to the PID sheet, it only needs the minimum RPM for the calculations. The 'shift point' and 'maximum RPM' only decide how long the white bar is, and where to stick the green arrow. But it does not seem to influence the 'suggested gear' calculation at all.

If what I am gathering is correct - the calculation simply says this;
"Can I go up a gear at this speed, without dropping below minimum RPM?'

Is that about the jist of the calculation? I would have thought it'd be a bit more complicated than that - picking best performance/efficiency.

The way it is now, as soon as I take off, it believes I can go straight to 5th gear at 40km/hr! Granted I won't stall the car, but it doesn't seem to make much sense...

Any clarification on the purpose of this calculation would be appreciated!
