I don't think the scale and timeline have been altered to the best of my knowledge. Unfortunately the PDF conversion has rendered the graphs in a relatively low resolution, but they're still readable.
What I was getting at (as I'm sure you're aware) was whether certain posters believe that the data was deliberately altered to say something other than what was on the DFDR, and what reason they have for thinking that may be the case.
For the record, I think the data is genuine.
