Its always good to follow your postings because they can seem to be linked togethrr.

Look at case of Djokovic where every day there is a change in metric that change the knowledge as you say in your two posts.

First he get dome exemption for positive PCR..

Next he stopped to enter country.

Next some newspaper say his test not positive.

So for each the conclsion is changed.

The PCR test is gold standardbfor infection detecting

The PC result cannot be trusted

The PCR result can be manipulated...so it cannot be trusted...( and you data can easily be found ) so possibly manipulate so it cannot be trusted.

So does it link this story of last two posts?

The story is still continuing.....

AP: Yeah, we want to know how he got into Spain...

It is true that there is always imperfection in any metric. If someone is really interested in improving metrics, they should re-evaluate the metric holistically, and they must restate historical data. Unfortunately, the latter provides an opening for fraudsters. It may not be possible to restate history. If they don't, that creates a break in the data series so that the historical data must be discarded. That's like stopping the match, changing all the rules and then restarting from 0-0.
