I only mentioned that because Larry mentioned normal distributions of results in a previous message and it struck me as strange to expect a normal distribution of scheduler latencies. He was arguing against using the minimum time from a benchmark, as I recall. There are a number of places this is useful number, for instance, the round trip times from ping. The minimum rtt is a rather hard limit and tells you what the best latency you can expect is.
