Dolor has 54K, but PLs don't show technique or Magic(it only rates Magic Power). That's the main reason they are so vague.
Meliodas's PoD is on another level. It boosts them but probably not as much as him.From 32,500 to 56,000? That almost doubles his freakin PL..... wait a second, does that imply that he could've easily reached a value around 150k with his full mark in that version that fought the 2 10C? Think about it, prior to getting any of his powers back he went from 3k (base) to 4k (partial) & then to a staggering 10k (supposedly full). This 56k value is roughly representing the 4k (partially Demonized) form. I could only imagine how absurdly powerful the 10k (fully Demonized) version would've been.
Wouldn't be surprised if we reached the 1 million value at this point tbh (this is the same author that made kongou banchou after all).
I'm even more hyped to see the Commandments at full power now since the Darkness gives them tremendous boost. Estarossa might be able to easily reached 100k with the full Darkness form & Zeldris even above that.

. No matter how you think about it, it doesn't make sense if you only consider their Power Levels. Just wait for their return, Dolor and Gloxinia will redeem themselves
