so let's say we're already exporting the rtt as time series data,
then to have the deviation from the series is just a matter of calculation...
you can do it on the router surely, but if you do it elsewhere then you
must be able to select a time range to calculate the deviation from just 
those...

the thing is that, it could be a completely different value:

please take a look at the below two pings... i tried to start them at the 
same time...
they calculate the deviation obviously the same way, the difference is the 
time interval,
1111 pings: min/avg/max/dev rtt=3/4.0/19/1.0
2222 pings: min/avg/max/dev rtt=3/4.0/19/1.2

probably, i had some more bigger responses when it ran twice the time and 
that's why the mean deviation 1.0 vs 1.2 mean deviation...
