Well, in 1975 the line was "look to your left, and look to your right, one of you will be here in 4 years." Not saying it was true, the they really made it seem that you would be lucky to survive.The rhetoric was "look to your left, look to your right, one of you three won't graduate," as best as I recall. That rhetoric corresponds to a 66.667% graduation rate. The figure I referenced noted 69% grad rate after 5 years, hence 2.333%.
