Tickets happen. This is far different than racing a camaro on the street. I tend to drive 5-10 mph over most of the time, and 15-20 many times when I'm out on country roads in the middle of nowhere. I have a radar detector.
The detector has helped me quite a few times, but I still have 3 tickets with my Camaro. Each of them was for 15mph over the limit. I would never say I didn't deserve them, and always treated the officers with respect.
As far as detectors go, two of the tickets I got I never even got a hit on the detector. The last time was an instant-on situation, and nothing I could have done. I even had my camera going on that one
