Yes; the calculation would be the (near) outer edge of the pickup screen diameter and the height to the bottom of the pan. Then, if you consider the ID of the pickup tube itself and that cross sectional area versus the invisible area created by the an invisible cylindrical wall from the screen area down to the pan.

Just a guess but that 1" inch height is 6-8 times the tube ID.

A lot of oil tends to loiter up top under hard / sustained acceleration (redline thru a number of gears). Conversely, that oil staying up top reduces crank windage...
