I have seen this published before, but the only name I have seen for this formula is "Buffered Borax".
I like the original D-76 (ID-11) formula, DK-76, Adox M.Q-Borax and an M.Q developer that I recently designed for one-shot use which is diluted 1+4 from stock and uses carbonate + bicarbonate instead of borates.
I use the carbonate / bicarbonate version as my standard developer. It gives similar tonality to standard ID11/D76 but a bit more sharpness that accentuates grain a little, which I like.
Try it with HP5+ (if you haven't already!)
What would be the 'real life' benefits of the boric acid buffered version?
