Subject: NPS, EBF, Knowledge and Elo

If doubling NPS (all else being equal) produces a roughly 40 to 75 elo strength
increase, then doubling knowledge produces how much elo strength increase?

Or do increases in knowledge follow a completely different type of relationship
to playing stength?

What impact on NPS does a doubling of knowledge have? I know it slows it down,
but what is the relationship (a rule of thumb) between the 2? It is said that
adding knowldege in hardware does not exact a speed penalty, but can this really
be true? Or is the speed penalty simply less apparent?

How much attention should a programmer give to lowering the EBF of his program
versus adding more knowledge?

I'm curious about the different opinions programmers have on this topic. My
assumption is the answers to these questions can have a big impact on computer
chess program design.
