Something like
 strength = engine + hardware + book

You say 700 for the book.
We already know hardware advantage to be in the order of 60 Elo per doubling, so
for a quad let's give it 100 Elo.

Shredder system performs at ~2750 at world champs, that means shredder engine
(single game, no repetitions) on normal hardware is less than 2000 Elo??!!

We don't have that statistics so to us it is guesswork.

You claim to have such data but what you say sounds wrong, it would mean among
other things that Frenzee (random book) is about 300 Elo stronger than Shredder
(random book).

Obviously something doesn't rhyme.

It couldn't be that you just underestimate the importance of the engine?
