Speed of light delay puts a lower bound on latency, but the actual delay depends on transmission error rate, buffer size, bandwidth, and utilisation. Assuming that the link is close to saturated, real life latency will be determined by how big the buffers are at each hop. Traditionally, internet providers have been optimising for bandwidth at the cost of latency. I wonder what Starlink does.
