The calculated chemical shifts are typically good to about a percent of the measured shift range, which is not unusual for properties calculated using DFT. The GIPAW approach is a general method for the First principles methods using CASTEP-10-5

A first principle is an axiom that cannot be deduced from any other within that system. The classic example is that of Euclid's Elements; its hundreds of geometric propositions can be deduced from a set of definitions, postulates, and common notions: all three types constitute first principles.
