So which points are getting “faster than fibre” latency because of this? Extra distance up and down, but make up for it on the long-haul.

Won’t beat HF radio though.

Starlink adds a latency penalty of tens of milliseconds going through the atmosphere. Each round trip is four hops through the clouds. I expect most of this delay is forward error correction, combined with lower bandwidth of the radios.

On top of that, you may have queuing in each satellite.

Finally, the satellite laser links aren’t pointing exactly in the direction you want to your packets to travel. They’re at some diagonal, and the packets need to tack back and forth, which wastes distance. Think the streets of Manhattan.
