Since this is what you (the developer of Joker80) recommend as optimum, 
this is what I will do.

Are you sure that replacing any pawn values different than 85 points
after renormalization to queen = 950 points still renders an accurate 
and complete representation, more or less, of the Scharnagl and Nalls 
models?

At par of queen = 950 points, the pawn value in the Nalls model
is not represented as being only 92.19% as high as that in the Muller 
model and the pawn value in the Scharnagl model is not represented
as being only 98.95% as high as that in the Muller model.

Thru it all ... If a perfect representation is not quite possible, 
I can accept that without reservation.

Correctly calculating pawn values at the start of the game (much less, 
throughout the game) requires finesse as it is indeed a complex issue.
In fact, its excessively complexity is the reason my 66-page paper on
material values of pieces is silent in the case of calculating pawn values
in FRC & CRC.  Instead, someone needs to read an entire book from an 
outside source about calculating the material values of the pieces in 
Chess to sufficiently understand it.

Personally, I am content with the test situation as long as Joker80 
handles all pawns under all three models initially valued at 85 points
as fairly and equally as realistically possible.

I cannot speak for Reinhard Scharnagl at all, though.

If you would subtract half the bonus, then on the average they would 
be what the model prescribes.'

Now, I understand better.
It makes sense.
[I am glad I asked you.]

Yes, I will subtract 20 points (1/2 of the 'bishop pair bonus') from the
model-independant, material values for the bishop under the 
Scharnagl & Nalls models.
