Thomas Knoll ?

thank you
my question was more about  each F/Stop records half of the light of the previous one, and therefore half the remaining data space available

f/stops are log base 2 scaled. If you use integer linear encoding the above is true regarding the data space, but if you used log encoding (already used in some HDR encoding schemes) you can use the same data space and have the same encoding accuracy in all f/stops.
