Tried to calibrate the controller using k-value adjustment. At k=7.49 the regulator outputs 9.3 liters instead of the default 10 (or -7%), at k=7.50 it outputs 10.9 liters instead of the default 10 (or +9%). I assume the correct value for k should be 7.494, but the controller doesn't allow for such fine tuning.
