Did Chest pull this out of an internal database?

No, if you are using AutoTurbo-mode then ChestUCI doesn´t use any special parameters from the database (although it just tells you if the position has been found), it recalculates the optimal parameters from the scratch.
Only if you use Special-mode then it would immediately use those pre-calculated parameters.

I will spend more time learning Chest settings.

A good idea!
At first you should probably switch to English language ...
(unless you want to learn German )

It's interesting that the "private" WB-Engine QUARK 2.70h by Thomas Mayer (I'm a friend of Thomas) is stronger here then Rybka!

BTW, Quark 2.70h is only a special Anti-Human Engine of Quark with an anti human heuristic, and is not identical with normally Quark-Engine.
