SpaceX Starlink Projected Latency vs. My Wave Cable Latency

SpaceX is claiming it’s Starlink latency will be similar to cable latency.

“Because of the low orbits, SpaceX says its broadband network will have latencies as low as 25ms, similar to cable or fiber systems.”

Network latency is an expression of how much time it takes for a packet of data to get from one designated point to another. Latency is measured by sending a packet of data that is returned to the sender; the round-trip time is considered the latency. This is called pinging.

I have a data file of recorded ping data from my Wave connection from October 25th to November 8th, so thought I would make a comparison.   A simple Python program produced this graphic:

The median ping was 33.87. If Starlink can maintain 25ms of latency, they will be better than my cable connection.
