What i sense is that each iteration to date, enables a range of thresholds, related to new content additions , and releasable keywords. Some keywords still remain "Pandalized" as a consequence of a site needing to go higher in it's quality score. If a site hasn't risen in the underlying Panda quality score, then these "so called" dynamic elements that rank newly produced pages will not rank.
It would appear that this threshold, and interim enablement goes beyond those individual new pages, and extends site wide.
I'm not sure if this was in existance before Nov 19, but I'm guessing it's a recent feature.
It will be interesting to see if the next iteration builds around this. It will also be interesting to see if such pages prop up an overal improving quality score, or get overidden and drop. But this is probably individual to each site.
My guess is it won't be this week, maybe later next week that another iteration will come through - but that's pure hunch based on previous patterns.
