doubling the number of samples increases the SNR by 1 bit assuming that
there is only thermal noise and that noise temperature remains constant
across samples. what measure you use for SNR determines by what factor the
number increases.

That's correct. But it doesn't add one bit of signal; the noise
level increases as well. That's where the sqrt factor comes from.
