Ah i see then.

Well you're explanation really works out well for here then. I would say that it does make sense if the character did alter the past in such a scale, he'd likely be Low 2-C or High 3-A. But since the OP said of a character doing such feat without ever changing anything to the present and future, i don't think it'd be tier-able then...
