Okay so the maximum base is 357 (I hope and if it isn't i'm going to flip a table)
In the case where the energy is in orange (Latent power activates), at Charge level 2 and also after 6 uninterrupted loops (Combo bonus effect) and also factoring power plus which is in base power anyway the max should be 1400.
In a proportional comprison to a level 50, base 210 power, when in orange energy level (I was at 9) it goes up to 312, in charge 2 orange energy level goes up to 722 and the combo bonus takes it up to 824.
Do the maths. it works. :L
And if this is wrong I'm going to flip Mewderator.
And please don't ask me if it should be proportional ._. It either goes up in percentage increments or set values. Nintendo isn't going to change the specific amount of increase for every level. If it goes up by set value the maximum would be 961.
Actually doing the maths makes it 1400.8, close enough
