It may be interpreted as an acceptable packet loss ratio at which
observed latency is common.

Or, it may be just that at the queue length for the latency,
RED algorithm of common routers start dropping significant
amount of packets.

FYI, if you ignore diffserve hype, it is easy to reduce latency
below 150msec with scalable per-flow resource reservation, though
it will be charged proportional to the length of reservation.
