One basic principle about using statistics is that you must remain consistent when collecting and analysing the data.

Once you deviate (include more or omit) the from the original data collection criteria, and method, the statistic essentially becomes useless as NO conclusions can be drawn from different datasets and you must start again from scratch.

But they know all this already but can bamboozle the public because they don't know how statistics can concoct any outcome if you are prepared to pay for it!
