Well I've answered this myself by experimentation, if I trigger the sensor at one point before the bed gets to it then print a bed level test the entire bed level is affected not just the level in this area.
When might we get a full bed surface compensation option? Why can't the code from RC's fork be integrated into mainstream marlin? I accept the arguments about flat beds and true objects but if you have a large printer a truly flat bed is difficult to achieve.
