Why might this page show limited data for Carolina?
We need at least 25 recent speed tests to generate reliable local metrics. If we don't have enough tests yet, the page focuses on maps and nearby locations while we keep collecting data.
What is the reliability score?
The reliability score summarizes how dependable mobile performance is in Carolina. It uses a 0.0 to 10.0 scale (higher is better) and is calculated from real-world speed test percentiles with weighted components: download (50%), latency (30%), and upload (20%). It evaluates the lower-end experience using the bottom 10%, 5%, and 1% percentiles when enough samples are available. If local speed testing is limited, a coverage-based fallback is used from signal quality distribution (great/good/poor).
