D76 versus ID11, Are they the same things ?

In scientific terms, these two are called Schrödinger Developers, i.e., simultaneously both the same and not the same when observed from a photography-devoted forum.
 

So basically it’s a blend of The Never-Ending September and Groundhog Day?! Ugh!
 
Perhaps each time we answer Umut's questions so thoroughly that he never needs to participate further but as koraks says we have said it all before and it's all already on Photrio, often in one long previous thread in the case of this question

It's called "SEARCH"! I have to admit that I have, on occasion, committed the sin of asking here before searching myself. 30 lashes to me with a wet noodle.
 




That suggests that D76 is somewhat more active than ID11 at higher dilutions. Perhaps the Ph is higher. Maybe Ilford skimps on the borax. Or perhaps the times could be the same and the results virtually identical. Maybe they think, if you use D76, you want your film to be lower-contrast - especially if you water it down.
