If you would do a flood ping it is more likely you will observe congestion
in the LAN when the probe is connected to a slow uplink. More interesting
for WAN measurements is the loss under 'normal' conditions. Consider the
probe beeing installed at a residential DSL or cable line, where one of
the probes I host ist located.

If I start a huge download I will have congestion on my upstream because
of the ACKs I send. A probe would now observe huge loss when doing a flood ping.
