Is no general rule. You need to find this for each vehicle because it's not as simple as staying the zone of best BSFC.

For example, part of the energy to accelerate is spent spinning up the rotating mass of the engine. That energy is greatest in the lowest gears, so the optimal shift points will be at lower RPM in the lowest gears.
