i would disagree with this. the main problem is that Nakaba never defines what the magical power levels mean. i.e. how much magical power can merlin use? this is conveniently never brought up.

as for "spell's she casts would have an initial strength of half of what the demon king could cast" is flat out wrong.

Merlin's perfect cube can hold back a cruel sun from Escanor who had a power level of 114,000.

Merlin's exterminate ray was unable to beat Chandler's version, until she used enchant infinity magic to boost the spell to the point where it instantly overpowered him. ignoring the vast, overarching question of why the heck she never used such a power, all Merlin would need to do would be to stack enchant infinity with power amplify, cast infinity to make it last forever, then stop casting, while the blast is continuing due to infinity, cast another exterminate ray, and repeat the above. it is never stated that she has a limit to how many times she can use a spell, plus, she teleported many, many times throughout the fight against Zeldris, so by repeating the maneuvre in the same place, she could make an unstoppable beam of magic. teleporting many times a second, which she is shown to do to avoid Zeldris' ominous nebula, she could create dozens  of beams in seconds. how to defeat the demon king? use magic seal on him first, then infinity amplify then power amplify. again, recast multiple times until he cant use "the ruler" because she has stacked 20 copies or so of a heavily boosted magic sealing spell. done. combine the magic seal to stop the demon king healing and cast loads of exterminate rays boosted and Merlin could defeat the demon king.

the problem is that the power levels flip on a dinme and the characters can only do as much as the plot demands.
