There's not really much difference between the top 1000 places, since all that matters is solving all 4 problems. This is the qualification round that goes on for 27 hours, so there is not much pressure to solve the problems fast. The Indian programmers are in a time zone that makes it difficult to get up at 4:30am just to solve the problems a bit faster.

Comparing the performance in the next few rounds would make more sense.
