I also wonder what the implications are as to what we measure ...
at the moment fping sends the icmp packets back-to-back
intentionally, to get a educated snapshot of what the link looked
at measurement time ... spreading the packets over the measurement
periode looses that advantag and goes into the direction of 'I want
to measure more often' this is already configurable by lowering the
step size so I am not sure this is a good idea ...
