New analysis: Planck data more in line with Standard Model than originally thought?

So Nature notes:
A new analysis of data on the infant universe released earlier this year indicates that the initial findings are more in line with the standard cosmological picture than had originally been thought.
Apparently, there is a possible “systematic error” in previous measurements at certain levels, aswll as calibration and mechanical issues.
“With an experiment as sensitive as Planck, the great challenge is fully understanding all of the systematics,” says Spergel. …
One issue is that slight variations can make a great difference.
Cosmologist Michael Turner of the University of Chicago in Illinois quips, “Precision cosmology is hard; accurate cosmology is even harder.”
Put another way, the universe doesn’t tell us when we are right. Or wrong either. We just have to keep checking.
