Interesting, thanks for you insight! So it might actually be worth to connect 'already connected' peers after all, cool cool. More experimentation possibilities 
It would be interesting to see how much someone might be able to earn running a LN node if they were trying to maximize their profit.
There are some writeups / articles online and also YouTube videos where people show their dashboard etc., but from what I've seen so far, to be profitable you need to put in a lot of manual work. We all know time is money & time is limited; so all that work for a few satoshi is usually not worth it. The 'maximum' profits I've seen so far, usually required a lot of BTC locked up + work under normal hourly wage.
