The IP may change once in several days (currently running over a week with the same IP and I just got my Stable flag back again, about 3 weeks after losing it). The relay’s throughput is a tiny fraction (less than 10%) of the actual capacity which I programmed the torrc file to donate. The capacity I wanted to donate is less than the uplink speed of my internet connection (the downlink speed is higher than downlink and is thus irrelevant here).

It is now 14, and never went above this again, with the relay running ALL THE TIME stably for a month minus a small number of restarts due to IP changes. As I said, stable IP for a week now and a Stable flag.

>> 1. Why is the relay with dynamic IP punished? This makes zero sense to me. IMHO changing an IP once a week and running stably between such changes is stable enough for all practical purposes. And since the fingerprint of the relay does not change when the IP is changed, dirauths know that this is the same stable node.

>> 2. The “advertised bandwidth” that I see in Atlas has absolutely nothing to do either with the bandwidth that I advertise (it is 3-4 times larger than what I see in Atlas) or with the actual data throughput of my relay (it is 20 times smaller than what I see in Atlas). Can somebody explain this?

For as little as $10.00 US there are VPS' with static ip's..
