Castle Creations ESCs and Servo Settings Calibration

When performing an ESC calibration with Mission Planner on my X8 it just never seems to complete. It flies OK but I cannot help but wonder if I am getting all I can out of the motors.
Below are the servo settings in MP and my castle Link Settings. Should these be the same? and if so, do I correct Mission Planner to Castle Creations settings, or vice versa
