We had all these discussions before, with numbers and calculus, when it worth and not to redo the testing. That is why I said "let's see the list". No need to argue. I too was one who rechecked sanerud's and other lists in the past, never found a missed factor, or a cheater. I am not spiding the server, but many people here do. Make a list. I will participate on re-TF if I think it worth.

The participant 1997rj7 has been spotted before as one returning higher percentage of missed factors:

At the time we spend most of the energy on sannerud.com. There was also an effort on KYOJI_KAMEI:

However, as a side project I had fetched work done by "1997rj7" and re-TFed his results. I spend less than a ThzDay in that, but found 3 missed factors if I remember correctly. I believe others checked some of the 1997rj7 work too. It is not that problematic to re-TF his early work. Nowadays, the server accepts the duplicated TF checks (without a credit), which will eliminate any further triple checking.

sannerud.com, KYOJI_KAMEI and 1997rj7 are known to have missed many factors. They are not cheaters, but the bad machine they were using makes their whole work less trustful.
