What you see is distance nozzle-bed when sensor triggers. At which that happens depends on when your sensor triggers and is different for any printer. Therefor you can modify the trigger distance so it matches your printer. The eeprom value "Z-probe height [mm]" is the distance nozzle-bed when it triggers. So if homing z and going to z=0 crashes into bed the value is too high and you need to lower it. Once it is set correctly for your printer leveling should result in correct level. After each change you need to relevel.
