When I could see the sign I began to accelerate to 55 mph
That was a mistake. The new limit starts at the sign, not before it.

I probably hit 55 just before the 55 sign.
Then you were doing 55 in a 45 mph zone.

The Trooper clearly states that he obtained the speed from his rear antenna, but also states that I was in front of him. He also states that he had the speed reading for at least 15 seconds. I am not sure if that is required or not, but it is not even 15 seconds from the point I started to accelerate to the 55 mph sign, so he could not have possibly has me on his radar in the 45 zone for 15 second. I have also noticed that there is an argument to made for not clearly stating the subsection of 46.61.400, should I open with this, or the fact that he states that he used his rear antenna and I was in front of him.
Sorry, I don't see any defenses there. If you got cited for 10 miles over it was because you were doing 10 miles over.

Seems like to me that if he was in fact using his RADAR in the rear facing direction and I was in front of him the RADAR data should be excluded from the evidence.
The antenna is multi-directional. Ask him when you get to court. He'll tell you.
