Didnt read others replies, but this is a story of when i was at course and a guy had the same case as you.

The guy tried to fight the same ticket, had soo many good questions for the officer and thought of everything he could possibly say to try to get out of the ticket. The judge still took the cops side though, and the cop said how he can judge speed by eye since hes has been doing it for xx amount of years etc.

Whats worse is the cop was doing this over the phone in court! which i think is bullshit. Cant even show up to court... so the police officer had no physical evidence to present, just his word against the defendants and he still won. You have a good point tho with your case and the guy never asked that question directly (for documentation of calibration)... Good luck with the case!
