I think you might not realize the obligation to provide answers rests on your shoulders.
This is due to the fact that you have made the central claim here—that a quantifiable amount of genetic change will occur in a continuous manner over a specific period.
However, your only support is a mathematical equation derived from observation of change in discrete instances.
So the only true assertion you have made is: if d x 20,000 = 0.01, then d x 2,000,000 = 1. But this does not in any way support the claim that genetic change will occur in a continuous fashion over 2 million years. The statement is provable universally only as a mathematical statement, not as a biological one.
What you have failed at, time and time again, is to provide any answer at all to what is going to STOP the inevitable genetic change in a population that is a result of the absolute impossibility for a living system to copy DNA with 100% fidelity.
DNA change in a population will occur continuously over 2 years, 20 years, 200 years, 2,000 years, or 20,000 years, 200,000 years or 2,000,000. DNA change in a population never ceases, because DNA cannot be copied with 100% fidelity.
So what is going to STOP this inevitable and inexorable change?
And again, the big question you have failed to provide any answer for time and time again.....
Why would bacteria have an lower fidelity DNA polymerase that is expressed during times of high stress?
