I've been trying to figure out the reason for our disconnect, and it just dawned on me the reason...I had assumed you were familar with Tillinghast and his design practices...you are not. If you aren't familar with his design practices over the years you obviously are not going to see the inconsistancy or compromise.
I've cited SFGC, Brook Hollow and Bethpage and you've explained it away, in your opinion those courses are of the PVGC championship variety as opposed to membership courses. Even if I agree with your description of those courses (which I don't, especially SFGC and the other Bethpage courses), there are scores of other courses that Tilly designed, nearly all his courses, from 1912 to 1936 that had bunkers in the 0 to 175 yard range.
Here is partial list: Shawnee, Quaker Ridge, Fresh Meadow, Ridgewood, Berkshire Hills, Beaver Trail, Newport, Illinois, Five Farms, Wyoming Valley, Lakewood, Binghampton, Forest Hills Field, Philadelphia Cricket, Winged Foot, Southward Ho!, Fenimore, Golden Valley, St. Davids, Sunnehanna and Norwood. All these courses have bunkers in that zone...it was career long practice...and the Depression did not stop that practice...see the Bethpage courses.
It also explains why you put so much stock in those two articles (the confusion with dates not withstanding). If you were familar with his designs (and the cop bunker for that matter) you would have immediately understood in what context he wrote chapter 32 (1920) and not confuse it with his later PGA transformation (exemplified in Chapter 28 -1936). Its hard to see a compromise if you can't recognize a change.
