that's a very interesting comment.

As to your question, No the metaborate solution was added as the third component, with the KBr last.
According to my dilution calculations (which may be incorrect), the required 35g/l of metaborate is equivalent to 140ml of a 25% solution + 860ml diluent.

However I have subsequently found a comment (can't find it again now), by none other an expert than PE, to the effect that Ascorbic acid can be temperamental in developers. Or at least that is how what I understood him to be saying.

As EAA is a "lab" developer, and my kitchen is certainly not a lab, nor I a lab technician, it's perhaps not surprising I've had inconsistent results.
