Practically take this as general reference, the images at the right side, (ignore the axis labeling and everything else, just pictures).

Thats somewhat a generic waveform or rising/falling edge. The ohms law give the end (top) value, but in practice notice that it takes a huge time to actually get at that. The driver needs to be fast. So the stepper driver needs to work with its own peak value where it interrupts stuff, and that needs to be in the left side, where the waveform is rising rapidly. In that area it rises rapidly, and it allows the driver to work at high frequencies with full current value. The more operating point is to the left, the fastest operation can be.
In practice that peak can be adjusted withing driver's limits, and depending on the driver and its settings it may or may not reach that peak value either (different driver's business). But at least thats what i think of the frame reference on motor picking, and what the parameters should point at.
