You know you can ask to see the radar gun reading, right? They have to indicate how they calculated your speed, and 90% of the time it is with a radar or laser. If they do it with some type of counting/distance method you can almost always fight that, especially if there is traffic around you. So the point is that if the ticket said you were going more than 20 over, you were. You can ask, but the officer has absolutely no requirement to show you the radar or laser. Most officers do not show you the reading due to officer safety factors. I wouldn't want a citizen sticking their head in my squad car where a rifle or shotgun is kept. Many, many, many times the officer does not even lock in the radar reading. It is not required. Many older radar units stop tracking the speed once the speed is locked in. Why lock in a speed at 70 if you can tell that the vehicle is still accelerating? The officer is required to estimate the suspect vehicle's speed, activate the laser/radar, and then track the speed for 3 seconds. There is no requirement to lock in the speed. Back to what nodakfan17 was saying. I agree that the original poster should take responsibility and pay up. It sounds like he is taking full responsibility for his mistake. However, if you know how to play the game, more power to you. In my opinion, it's like trying to get the best price on a used car.
