> half as much, resp 1/4 and 1/8 as much hits No. These errors are very rare. You only get any of them (according to the hypothesis we're considering here) because there are so many DNS requests made. The probability of getting two bit-flip errors in a single request is much smaller than the probability of getting one, so the expected number of 2-bit hits would be way less than 1. Something like this might be a useful check in a different way: bit-flipping errors will almost always be single-bit errors, whereas typos and suchlike won't. So if the bit-flipping theory is correct, you'll see systematically more single-bit than multi-bit errors.
