Ouch! I've noticed it makes quite a difference even if I run my tyres a bit softer. That is a real shortcoming on the purion.
I guess not many people will bother to change their display when they change tyre pressures even if they could. Though on a display where it is easy they might just remember two or three settings for different tyres/pressures, and try to set the correct one.
