There were 150 candidates you scrubs, half got screened out by the inspections, leaving 75 actual subjects. Half of those were fucked over by the augmentations, leaving you with 32, I believe. 30 died by the augmentation, and 13 were injured beyond normal service.

There should be no number above 150, but Bungie keeps breaking their own canon, unless there's another list not mentioned that was narrowed down to the 150 we know of.
