Hi Paul.
Yes, recording actual test results has proved useful. We found a mains transformer which was gradually getting leaky, had a replacement made (which took weeks !) and replaced it before it had a chance to cause any problems.
We are just on the point of getting the COBAC computer system up and running, so we will be recording everything on there - but will probably still keep the written / printed test results as a backup / reference.
You're right - you never know when someone might ask for them - like the Coroner !
