LHCf and high-energy cosmic rays

I don’t have any more news.

It took physicists by surprise when analysis of the data collected by the two LHCf calorimeters in 2010 showed that high-energy cosmic rays don't interact with the atmosphere in the manner predicted by theory.

"Given the significant disparities between the theoretical predictions and our experimental data, I believe that physicists specialising in this research field will be obliged to re-visit their results in the light of this new information."*

I don't see a disagreement between data and theory. I see a range of theories with a factor of 2-4 average variation and the data lying inside this range.
