You will always be uncertain.
It is always possible with probability that is more than 0 that a program that
played random moves will lead the ssdf list.

If you are sure in 99% you are also uncertain.

The probability of confidence is based on some assumptions when the assumptions
are wrong.

Some examples for wrong assumptions that the ssdf use:

1)The result of games are independent events(false, programs learn).
2)The probability for white to win is the same as the probability of black to
win(again false).

I agree that the reality is too complex and I know no good mathematical model to
represent the reality so I prefer to trust my feeling about evaluating the level
of chess programs.

Without doing it I can only say that I know nothing and even do not know the
level of confidence.
