Opinions on this unique speeding ticket and likelihood of outcomes.

I was driving in upstate NY at night. I turned on to a state road and my GPS said the speed limit was 55 mph. I verbally said to my partner, "55 does not seem right, this feels like a 35 mph zone" and it was just a feeling. At this point, I was not going 55mph, I was just driving cautiously because it was dark out and I didn't know where I was going. At some point down this road, I finally see a speed limit sign saying 45mph.

About a mile after passing the 45mph speed limit sign I get pulled over. The cop wrote me a ticket for going 48mph in a 30mph zone. When this happened I pointed at the speed limit sign (a new 45mph sign was right in front of where I was pulled over) and the officer told me "I saw you back by the cemetery where it is a 30mph zone."

I did not say anything and just took the ticket and went on my way.

The next day I did some research and did see that there is a 30mph sign right before the cemetery which I did not see. The 30mph zone is about 0.4 miles long and then the 45mph zone starts.

My ticket says "Charge based on Officer's Direct Observation" and "Speed Verified by Radar". Now to be truthful, I have no idea how fast I was going through the cemetery, but I do not think I was going 48mph because I remember speeding up when I saw the 45mph sign which is after the cemetery. The cop also pulled me over 1.4 miles from the cemetery. I am going to court to fight it based on the assumption that the cop saw me at night pass her, she perceived me to be speeding, but didn't confirm my speed until I was in the 45mph zone. My ticket should be for going 48mph in a 45mph speed limit zone, not 30 mph zone.

Side note: I did the math and assuming I was driving 48mph the whole time, it would have taken me 1 minute and 53 seconds to go from the cemetery to where I was pulled over. That seems like an awfully long time to get pulled over if the cop had got me on radar at the cemetery.

What are your thoughts on this argument? This is my first speeding ticket.
