You are probably losing the first ping for reasons unknown.
The FPing probe has blazemode to discard the first ping, try that. http://oss.oetiker.ch/smokeping/probe/FPing.en.html

Subject: [smokeping-users] Bug: constant erroneous packet loss
I'm running smokeping version 2.6.8 on a Raspberry Pi.
$ ping -c 500 184.108.40.206 | grep -A 3 statistics
--- 220.127.116.11 ping statistics ---
500 packets transmitted, 500 received, 0% packet loss, time 499746ms
rtt min/avg/max/mdev = 7.954/14.005/56.465/7.723 ms
I have no packet loss when I use ping.
When I use SmokePing, I get the following graph:
packet loss: 20.00 % avg 20.00 % max 20.00 % min 20.00 % now
One out of every five packets are reported as missing. I had changed the fping frequency from 3 (where I was getting a loss of 1 in 3, or 33.33%) to 5 (where I was getting a loss of 1 in 5, or 20.00%).
At first the reported loss was only to a ping to google. Then I stopped the daemon, cleared the rrd data, restarted SmokePing, and the "loss" went to the first hop outside of my router. I repeated the process and now the "loss" is on the second hop outside of my router.
Bug? Is it known? Is there a patch?
