There’s some games where I lose to stronger players ~15 or so games down the table the deviation goes down slightly (62.5, 62.4 ish) then I lose to a lower rated player and it starts going up, 63, 64 and the other wins aren’t actually brining it back down until maybe the third entry but then I lose again a few times it goes back up, particularly when I resigned today against a 5kyu.
Amybot ddk for example is very different, the volatility is pretty much maxed out I think. I don’t think it can go above 0.15 for instance.

Probably it makes sense since the bot has crazy results all the time, beating 13kyus and then losing to 25kyus. It’s almost a definition of volatile 
If I get back to a computer I should try make some graphs or something to plot volatility, deviation and outcome against each other some how and see if the behaviour is consistent or intuitive in some way.
But it does look like say Amy it’s deviation changes a lot more because of the high volatility
