Of all the numbers the most fictitious is the 20-40ms latency. I've averaged 55ms for the last month and it's basically been that way since February 2022. The variance is wild too, 25-150ms is common.
Xfinity provides "800-1200 Mbps service" in many areas and they don't even mention upload speeds. You can expect less than 50 Mbps for areas, though their official press will advertise "eligible xFi Complete customers can receive up to 5–10x faster upload speeds" [2].
