-The calculated percentile has roughly millisecond precision. If precision is of
-importance, read on for a more detailed explanation. In order to calculate the
-percentile without keeping all replies in memory, I<oping> divides the
-I<interval> (the B<-i> option) in 1000 "buckets". Each bucket counts the number
-of packets received in the represented time. That means that the precision
-decreases if the interval is increased, because each bucket represents a larger
-(fraction of the) response time. The code looks for the first bucket
-representing at least I<percent> responses and returns the upper-bound latency
-represented by that bucket. Since the represented percentage may be larger than
-the configured percentile, this algorithm I<overestimes> the actual percentile
-by at most 1000th of I<interval>.
+e.g. if B<-cE<nbsp>5> is given, the default is I<80>. The calculated percentile
+is based on the last 900 packets (15 minutes with the default interval).
