It does seem that, with a very few exceptions, the "do as I say, not as I do" approach ruled the day. What's interesting is that, for everyone to agree (i.e. to say) that fewer bunkers were better must mean there was some definite cache attached to saying so. (No one says it's better to poke your eye out with a stick than not). And I think that cache was all about demonstrating that you understood how great architecture allowed the beginner (the rabbit) to have fun while at the same time tested the scratch man (the tiger). The fact that, in the end, most architects over bunkered their courses suggests that maybe, just maybe, they weren't all that concerned with the rabbits; and that they knew that, in America at least, it would be the tigers (and paper tigers) who'd be footing their bills at private courses.
