Laser Filament sensor calibration Data

[X30N]

My filament sensor shows currently in the Calibration Data a minimum of 0%, avg 130% and max 185%.
Are these valid Data?
I use one of those Designs that measures movement indirectly over a bearing.
My previous calibration had a minimum of 10% and max of 180% but "falsely" triggered multiple times a too little movement error and destroyed the print
( my pause.g had a retraction of 10mm, but because of a new titanium all metal bridge it should retract around 1mm, my fault)
Most example calibrations shows an >0% min, so I am reluctant to put the 0% in my config.g
