Sure. It’s reasonable to say “you will probably not be ticketed for going 5 mph over the speed limit”, but that is not the same as saying “it is legal to drive 5 mph over the speed limit”. Hell, where I live you probably have to go 40 mph over the speed limit before the cop is even going to wake up.
Speed cameras typically are set to 10%+3mph to account for variations in speedometers/tyre pressure etc. At least in the UK.
