Thinking on the OP post, I'd say he has a high 3-A character based on this:

>> lets say what i am thinking have about half 4D power from full 4D power (meaning low 2-C).

So he means that his character has SOME notable level of 4D power but less than what a Low 2-C has. And what he wants to know is, if a High 3-A character such as this one could do something such as altering all of the past.

Then his question:

"Can this level character example rewrite universal space continuum past only but not future or destroy past leaving future unchanged?"

...A High 3-A is unable to do that, as he would have to affect the Past in a Universal scale to do so. If your character has a feat such as this one, then he's Low 2-C. Our world exists inside Space-Time. For each smallest fraction of an instant in space-time, our Universe is "present". If you alter all of the Universe's past at any given point in time, you're naturally Low 2-C, for you used Universal 4-D power.
