I can't answer your override/multiplier question directly, but I have been following the excellent guide at https://teachingtechyt.github.io/calibration.html#flow which has you print a topless cube with a single wall. Adjust the layer width to match your nozzle (and make some other adjustments), then print and average the measure of the thicknesses of all the walls. Plug in that number, and the webpage will calculate your needed flow rate.
You could use this to determine the override/multiplier issues.
