Well... a lot of time pass and the node is as healthy as ever. When your reach a good number of channels with good amount of bandwidth there is almost no need to rebalance via software, spamming the network by your own, others nodes are already doing that.

- You use less processing power

- You use less network traffic

- Accounting (for your own) is a lot easy

- If you have a Tor only node, it's a must

What else you can do:

- Loop out when the time is right

- Use the biggest amount you can

- Close channels with no traffic

Next experiments... set and forget ppm (in progress); reduce max_htlc per channel to lower failed routing.
