Indeed, his solutions are balanced close to the point of max.
solubility of AFO at room temperature, which is 1.4M (~ 60% IIRC)... I
personally opt to use 45% AFO with a Pd solution precisely balanced to
it. I get pretty convincing blacks that way, therefore haven't felt
the need of trying something stronger - which I'm perfectly sure will
give better results in terms of speed and dmax...
