I don’t know where you got your information from, but BCH didn’t even get bigger than 8 MB block post fork. So it STILL trumps BCH even considering your information.
Actually during the stress test last summer we saw thigs got tricky with blocks over 20MB. This is why helped highlight the need for the upgrade, and what the bottlenecks were.
I see now. You’re one of those that wants to “protect” miners from big blocks. In that case, youre just slightly better than Blockstream and you will fail as BSV smokes BCH.
