Hi ZmnSCPxj,

Just a nit to add for reference to this great writeup.


> - Add random tweaks to your channel traversal costs.

> - [This paper](https://arxiv.org/pdf/1909.06890) evaluates the C-Lightning route randomization as well.

Since the authors made this analysis, the total fuzzing has been replaced by a tweak of both the base and proportional fees, added along the CTLV during the shadow route random walk.
