I always found the screening device to be accurate with those I arrested for drink drive,
occationaly, someone blew one or 2 points under the limit on the evidience test, but that would be accounted for by time difference between tests and the BAC going down.
The same applies to when the Evidiencial screening test machine was not available and blood was taken as an alternative, if the result came back under it was by a margin that would be expected in the time between original test and the doctor arriving at the Station to take a blood sample.
ie They were guilty really but got away with it.

The point i was highlighting is just because someone provides a positive screening test, it most definately does not mean they are guilty ......
Two former policemen.
Two very different approaches.
