The search for a D-76R substitute...

Only the published formulae are the same.

In practice the commercial versions aren't exact clones any longer. Kodak altered the buffering of D76 adding Boric anhydride some years ago. pH's and activity will be slightly different so there will be variations in dev times etc.

I defer to your superior knowledge Ian, I must admit it's more than twenty years since I did any monochrome darkroom work and my information is obviously out of date, but it's still probably as close as he could get to the original.
 
Darkroom cookbook. I make plain D76 from it and it works perfectly right out to 6 months when it starts to die just like the package mix. The replen is a published formula.
