The regulations states that the speedometer can be up to 10% out of calibration on the high side (reads a high speed than you are traveling). Low side tolerance is 0%. This way, if you speed, you are definitely speeding, no if's and's or but's about it...
In the USA (some states anyway), you have a right to access the calibration report for the radar in question. If it is over one year old, you can have the ticket dismissed.
