Don't discount the increased number of applications at the top 10 schools. It's entirely possible Stanford has an extra 500-1000 apps this year vs 2009.
It's possible that apps have gone up, though it also seems like a couple years ago was the peak in the MBA app boom. But regardless, if the class size hasn't increased since 2009, then we would probably expect the #s of interviews to stay about the same regardless...just with increased competitiveness for each spot.
