So this means things like the entire radar manual should be considered obviously relevant and should fall into prsoecutor disclsoure. It also means that speedometer accuracy is also obviously relevant (if the speedometer was used to either pace or test against radar).
And notice in p  that for intoxilyzers, they normally give logs, diagnostic tests AND calibration checks as first party stinchombe disclosure, so it would not be unreasonable to ask for these with respect to radar/laser as well.
You're making a leap. It's like the disciplinary records that you quote above; not all records are relevant, just certain ones. The same could be applied to radar records.
This is no golden bullet.
