Mine were not really calculations, more like numbers pulled out of the air to illustrate a concept. Your numbers seem about right.... most DSLRs have a full well somewhere around 40,000, and your range of 10,000 to about 100,000 bracket that nicely.Don
something wrong with your calculations I think. Pixels have full well (max. electron counts) in the order of 100,000, not 2^14.
DR is 20 log(full well/noise) so if noise is 10 electrons and FW 100,000 that makes 80dB DR, just over 13 bits. Though smaller pixels may not reach 10,000 electrons FW, and noise might not be as low as 10 but the best pixels can reach 2.
