Guessing that's the reason for the discrepancy... Added filtering to data series before computing the median, and a new column that shows the loss as a percent of data points filtered out. Probably going to get in trouble for calling it loss, since it does not correspond to packet loss (except for ICMP flows), just to lost data points; not actually sure it's a good idea to have it in there... -Toke
