We present first analytic calculations for commonly used substructure tools, namely jet mass distributions with trimming, pruning and the mass-drop tagger. These calculations lead to significant insight into the behaviour of the different substructure algorithms, especially in the very boosted regime. They also indicate how one can obtain variants of the above taggers that have better theoretical behaviour and that improve on our ability to distinguish signal and background.
