By writing f for the third leg, you fail to make it bend there, so that what you wrote are in fact just needlessly complex notations for Griffon and Manticore. To make a 45-degree deflection you need fs, but since you don't want the trajectory to branch there, you must specify in which sideway direction you want to bend. This is l for some trajectories, and r for others, but always opposit to the way you bended after the previous leg. So that you can use z to describe all trajectorise, rather than having to split in a left-then-right and right-then-left group. So WafsWafsyafzW. The bracket notation [W?fsF?fzR] also works for this, alleviating you from the necessity to specify the first two steps separately by use of the 'optional continuation' symbol ?.

In a future version it could even be simplified to [W?F?fzR], but currently the fs in the second leg is still necessary to indicate it must be an F step. (When expanding the bracket notation the later atoms are currently ignored apart from their leaping/sliding aspect, and the direction is purely derived from the directional prefixes.)
