The reason is that each measurement within a given percentile reflects a real latency that actually occurred. Latency is typically calculated in the 50th, 90th, 95th, and 99th percentiles. These are commonly referred to as p50, p90, p95, and p99 latencies. Percentile-based metrics can be ...
Whether the p99 value is the average or max latency of the 99% of request. Take above as an example, if there is only one request took 9168.2ms, is the p99 9168.2ms? Member hassy commented Oct 16, 2019 median is the same as p50 (and not the same as average, Artillery does not...

Latency is typically calculated in the 50th, 90th, 95th, and 99th percentiles. These are commonly referred to as p50, p90, p95, and p99. Percentile-based metrics can be used to expose the outliers that constitute the ‘long-tail’ of performance. Measurements of 99th (“p99”) and above...
