Abstract
I give a very short introduction to Chiral Perturbation Theory and an overview of the next-to-next-to-leading order three-flavour calculations done. I discuss those relevant for an improvement in the accuracy of the measurement of in more detail. One major conclusion is that all needed low energy constants can be obtained from experiment via the scalar form-factor in decays.
