I agree with this, don't exclude extremes because a blog post or comment said it was bad, they can still be useful sometimes. For general purpose web development response times, I like to refer to p99 and p95 for general healthiness. P50 doesn't do much more than make me feel better. Max has its uses, it can be a good timeout gauge as the commenter above me pointed out. If the RATE at which max values occur changes, you may have something worth investigating.
