I an well aware of that, because I have a Zen 3 with the nominal maximum turbo frequency of 4.8 GHz, but there are 2 cores which sometimes go up until 4.9 GHz.

Above I had given a simplified explanation.

You are right that a clock frequency higher than the nominal by 1% is not a reason for exclusion. However, most really overclocked computers are easily distinguished when looking at the complete GB5 results, because the clock frequencies differ by at least a few hundreds MHz from the nominal turbo frequency.
