Yes, I'm still focused on how 2015 is doing compared to the 2013 and 2014 rebound years, and as the volume increase over the past month was lower than that of the previous two Octobers, 2015 has now just dipped below 2013 (30 km3 less volume), while the difference with 2014 is still 1138 km3 less volume.
At the same time the volume increase of the past month was much larger than that of October 2007, and so according to the PIOMAS model 2015 now has 388 km3 more ice than 2007. And the already large difference with 2011 and 2012 has increased some more to 2296 and 2450 km3 respectively. But these months saw quite a steep increase during November and December, so I expect the difference to become smaller again.
As soon as Wipneus posts his detailed PIOMAS volume graph, I'll put it up here.
We see that the trend line on the PIOMAS sea ice volume anomaly graph has crossed the linear trend again:
