Yeah, I was thinking that if you added up all the IIT placements, they would be second only to MIT, but perhaps it's not fair to add them up like that, because each one is a separate institution.
and the table doesn't include Kharagpur (and Roorkee, Guwahati) because their percentages are smaller. It is conceivable that if they were all added up, they might even surpass MIT. But as you said, its not fair.
