There are some tests out in the literature. As long as you have regulary
secondary structure it is probablye quite decent. I have done some
comparisons in a paper (Conformations of Gly-X-GLy peptides and
comparison with NMR experiments), you can download it from my homepage
below. Please look at the references in the paper especially.

Groeten, David.
