How did you come up with the number 763? I would think there are 34 * 22 (minus one if you don't have an empty wave) = 323 waves in the original granger-filled scenario.
Ah, you're right killing time. I made an algorithm and the execution missed some sets, and after realizing what I missed I did a bit of tweaking to get your result of 323 waves. Thank you for correcting me. (Obviously your method was much faster...)
(And to correct my previous claim about the waves without the grangers, it would be 107 waves, not 179)
I forgot to mention a couple more armor attributes: helmet radar radius, and helmet frequency
