Summary[]
In power scaling, when we talk about characters, we usually say: "Within this media, the character consistently performs the following feats", which allows us to place a character at a given tier. Inconsistency would be something that doesn't fit into the consistent interpretation you already have. That can be caused by many reasons, like your interpretation not being consistent, or you may not have an explanation yet. Inconsistencies should be something you strive to explain, not this pimple you're letting fester.
