1/400= 0.0025
3/160 would be the same as 7.5/400, which is vastly larger than 1/400, seven
and a half times larger.
3/160= 0.0188 whichis 1.88% which I rounded to 2
8/160= 0.05 which is 5% exactly

I don't see any extra zeros. Where are they?

The predicted mutation rate of 0.0002 (2%) times 100 equals 0.02, according
to my calculator, unless there is something logically wrong and not
mathematically wrong.

I used the same math equations for the rest.

Is there something logically wrong? I think the math is correct.

I think 1/400 is in the ball park of average rate, at least that's what I
use for back of the envelope estimates.

1/400 = .0025, so I think you got extra zeros in your rates.
