Can you elaborate on this? I think I understand but, I want to make sure...in particular, what is meant by 'stability'?

Is it the...hmmm, say the activity of the developer that is unstable over time (as in the shelf life time) ? Or, is it simply "photographic properties" generally that are unstable over time (again, I'm assuming storage time but, perhaps, even over the development time?)

Let's take an example...

Compare the published D-23 receipe to say, D-23 plus 5grams per liter Borax (I believe the Borax actually increases the ph in this case but could be wrong).
