First of all, please stop quoting large texts, it just makes the thread a little more confusing
As for the Meliodas vs Mael thing, we never actually saw them fight, Demon Mark Mel when they met was portrayed as equal to an unknown time of Day Mael, all we know is that throughout the main series, at Full Power, they are said to be equal, meaning Prime Assault Mode Meliodas is equal to Near Noon-The One Mael, we have no basis to compare Prime Demon Mark Meliodas to Afternoon Mael, because they were never compared or ever fought
As for Elizabeth and Ludoshel, yes they were said to be on similar levels, however featwise, this just isn't true, Ludoshel got wrecked by Indura Derieri and Monspeet, while Elizabeth was able to overpower them both by herself, Ludo just ain't that impressive compared to Elizabeth, hence why Ludo gets Low 6-B, while Elizabeth gets at least Low 6-B
