Getting a 2:1 or greater risk-reward ratio on LN node and channels

WIP

Lets say a user wants to spin up a node with 0.1 btc, open a few channels, and generate routing fees.

How do they calculate a risk/reward ratio (RR) that makes economic sense?

What else can they do to improve the calculation, such as compartmentalising risk into discrete chunks which can be evaluated independently?
