The time scale of the bottleneck?

On the other hand how much genetic difference could have accumulated since the hypothetical split from our common ancestor with the chimp about 7 million years ago? (or is it 5 million, or maybe 13 million?). Can you tell me that? If the genetic difference is less than that figure then perhaps the hypothesis is possible; but what if the genetic difference is greater? Perhaps 95% similarity (5% difference) is already more than can be supported by evolutionary theory.

I’ll leave one explanation up to @glipsnort:
Evolution is a faith because common ancestry doesn't add up - #24 by glipsnort

Also from his article I linked earlier the genetic difference in humans that’s due to random mutations looks like this:

And this difference between humans and chimpanzees looks like this:

The pattern is identical and it mainly just differs in scale. The y-axis is higher in the human-chimpanzee graph than human-human. But because the overall pattern is conserved, that means that the same mechanism of leading to diversity among humans - i.e. random mutations is the main mechanism leading to diversity between the human and chimpanzee lineages. There’s simply just been more time since a common ancestral population.
