Whoa... that's an interesting calculation. Just one thing I need to point out: there would be a lot more Pure Titans than you estimated, since it took nearly a year for the Titan guillotines to clear all of them out. Plus, if there had only been 535 of them, you'd think that the operation to reclaim Wall Maria (with 250,000 people in it) would have been much more successful :)
