Paper developers are sometimes made up without bromide with the intention that some bromide will be added to the working solution. I suspect this may be the case with Gene's formula. Paper developers need bromide. The amount in the E-72 formula is the same as that for D-72.

I noticed that your formula contains bromide and Gene's doesn't. I realize this is an antifogging agent but how much difference would it make if left out?
