PSA: START HERE! Calibration made SIMPLE & please SHARE User Tips!

I must seem to be missing something here. The calibration tests in the Orca do not let you change layer height. For example: The max volumetric speed test when using .8mm tip is .64 and if you try to change it it will just mess up the output code. Obviously these tests are custom gcode to be able to print a part with different flow rates at different layers.
A layer height of .64 with .8tip will obviously produce a much higher value that say .24 layer height with same tip. What am i missing?
