No school boy error, just trying to sift through the information as you don't quote anything and provide links to the specific evidence. On this KCL letter it seems odd you claimed no link yet have a copy of a document that no one seems to have made publicly available.
Can you confirm the test dates that are relevant, because at the moment people are expected to take your word.
I note you now say "there was no calibration data" not they did not do the calibration. Which is it that the letter you can't show everyone actually says? Actually don't bother answering that unless you can show the letter. You accused another poster of being the opposite of evidence based, but you don't provide the evidence on this point, including on whether it was a requirement to give the panel the data (it seems it wasn't from the fact they didn't need it to reach their conclusion).
