That’s really difficult to pin down since it varies around the planet depending on your proximity to the Starlink ground stations, the latency from there to where you’re going (SatelliteGuys, of course!😉), and the number of Starlink satellites above your location at any given time.
Just now 11:00 AM Pacfic: 145Mbps Down, 11.9 up. Latency 25ms. Eastern Washington. I've seen it as low as 48Mbps down in the evenings and as high as 297Mbps down during the day. Latency pretty consistent at 23 to 30ms.
