In Nanatsu no Taizai season 2 episode 2, it's explained if Meliodas makes clones, his original power level is divided by the number of clones he makes.
For 1 clone, the power level is 1685, which seems correct.
However, if he makes 4 clones, their power level will be 420 each.
Mathematically, 3370 divided by 4 is 840, and when divided by 8 is 420.
But, why is it 420 not 840? Is this a mistake on the anime production?
