What is increase of current directed to extrusion motor for each increase in Manual Extrusion Speed?

I've located the rails on the Rambo 1.3 board on my taz 4 that supply the motors, and have been trying to measure the current directed to the extrusion motor for each speed setting. I'm doing this so I can avoid calculating all of the phases of the stepper motor itself. But it's proving to be difficult to measure still, so I was wondering is there is any documentation or data available on the increase of current per setting?

    I would check the rambo documentation for it. In our regular config file it reads
    //#define MOTOR_CURRENT {135,135,135,135,135} // Values 0-255 (RAMBO 135 = ~0.75A, 185 = ~1A)
    #define MOTOR_CURRENT_PERCENT {53,53,53,53,53}
    so maybe you can simply interpolate here.
