Speeding Tickets: Speeding Ticket in Bothell with Visual Estimate and LIDAR

My question involves a traffic ticket from the state of: Washington , King County - Municipal Court of Bothell
I have read numerous posts on here that have been incredibly helpful. I filed my discovery request using blewis advice. Here are my docs and defense.

My hearing is on Thursday (and I know it's not ideal timing wise) but thanks so much for any help. My question is:

1. Why does the officer mention his visual speed estimation capability several times ?
2. He has mentioned that he "checked the Lidar Unit's Calibration internally and externally using : internal self-diagnostic check, HUD aiming reticle alignment check , fixed distance check and delta distance check , before and after contact with the defendant. LIDAR unit was determined to be functioning correctly, before and after stop with the defendant." - DO they really do this after every infraction ? or is this a general statement that i Can argue against , "Functioning correctly" being vague ?
3. He mentioned LIDAR reading of 66 MPH at a distance of 374 feet" , Is this distance within the spec of Kustom Signals Pro LAser iii
4. Most recent calibration testing was done April 11th , 7 months prior to the infraction - But Kustoms Pro does only evrey 24 months. Any chance here ?

Do I have any arguments against the prosecution or do I plead guilty prior to hearing ?
