My name is Dave Chaplin, not Chris. I spent hours presenting the entire testing research to the National Audit Office, which formed part of their reporting into the BBC mess. We did a bit more than just play with the site. We hired lawyers and ex tax inspectors and went through hundreds of pages of legal cases, and put them through the tool, producing 511 pages of evidence. The research and conclusions were published in the public domain as part of a whitepaper on the CEST tool. Journalists, like Rebecca Hill, also do their own due diligence before writing their articles. She has all the evidence too. When you have gone to the same lengths as us, please come back and publish your evidence and let us know where you think we went wrong.
