Actually if we had so reliable measurements for that period like we do for last hundred years, it would not be hard.

Your arguments have no basis, just an attempt to distract from the facts by grasping for what is not being discussed (e.g. 400 thousand years precise inference). Given the information we do have we have very good understanding of the relevant phenomena.
