So, you obtained his training info and the syllabus used in his training course?
When I was a training manager, I recall my officers being trained in visual estimation on freeway speeds as well as lower speeds, and there were a significant number of such estimations. And, since we are not talking about even +/- 2 MPH, we are talking about deviations of, perhaps, 5 MPH, I suspect the court would be comfortable with their estimation. I was not radar trained (though I was a collision investigator), so I do not have firsthand radar training experience, but, most of my officers were.
