Each bit in SNR is 10 times the signal and each stop 2.

It is not percentage difference but by how many times.


Chris, first we are talking about tonal range and not SNR. As I mentioned the SNR difference is quite notable and Bill Claff measures it as even being bigger. For tonal range 1/10th of a bit is pretty small any way you measure it and speaking of measurement, we don't know the error in measurement (i.e., the precision with which they it be measured) so that is one more reason to interpret such a small difference with caution.
Oh, and I do know about the scale for SNR.
