You are reverting a number of well-sourced, carefully checked points.

You claimed that "there are severe data problems" without saying what, or even which points. 

I am trying to edit in good faith. You are taking four days of painstaking work and removing all of it without good reason.

I'll say it again: you can edit points you don't like. If you are convinced it is worth removing four days of work, why have you not taken the 30 seconds it would take to enlighten us about the data problems you found?
