The standard approach to pressure advance assumes that the rate at which filament exits the nozzle is determined by the force provided by the extruder motor, and that other forces are negligible or constant. Start and End Value for the Pressure Advance determines the range that the test pattern will cover. Input shaping alters toolhead motion in an attempt to reduce vibration and ringing. Keep in mind that the whole point of the PA calibration print is to go through a range of potential PA values -- some aren't going to work.
