I never found any Poser docs for the math behind any of the nodes. I reverse engineered everything.
Your bias is correct. You can actually verify this by hand, building a ** (log(b) / log(.5)) in nodes and then take THAT node, subtract with an actual math:bias node having the same inputs, then take the absolute value of that difference and multiply by 1000 and plug that into ambient_color. If there's any deviation it will show up as not black. Here I used U and V as my two inputs, and the lower four nodes do the explicit math. The upper two compare and amplify differences from the real Bias function.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
