No, this absolutely checks with my experience - I chase 5 and 10ms improvements all the time because we've measured and know it increases conversion.
But it makes sense, too: if the metric here is average latency, that doesn't mean that some users didn't see a much more dramatic increase. Every tiny bit of frustration removed from the experience adds up.
