An interesting thing to note is that it is an established fact that the mean number of photoelectrons can be estimated as the mean number of photons x QE, therefore, (mean photons) = (mean photoelectrons) / QE.

Isn't that simply the definition of QE? Or at least the effective one used and calculated by everyone?
