I think that you are wrong. My source is https://xmrig.com/benchmark/
Go somewhere to the middle of the page (to get rough middle performance CPU). For example I can see:
984 Intel® Core™ i5-10500T CPU @ 2.30GHz
(6 threads CPU).
I click it and mean hashrate is 1839. Divide that by 3, you have 613 hashes.
I have seen that at same time the https://miningpoolstats.stream/monero shown a 42% (not 51%), so I would rather trust that 42% number (it can not be faked?).
