Peter,
Equipment has changed so much, it’s very difficult to know, much less replicate, the intent the ODG’s had in mind when they did their thing. Dimple patterns alone have changed the flight of the ball, and the ODG’s obviously weren’t designing for 100 years later....I’m certain that, while they knew equipment changes were inevitable, the ability to understand today’s game wasn’t possible.
There is a par 3 at Barton Hills (Donald Ross) that is over 200 yards, has a deep chasm between tee and green, and the green tilts from front left to beck right. There is a knob just short and left of the green. Knowing that most every golfer would have to hit everything they had, with a ball that didn’t get too high off the ground, it becomes easier to imagine what DR was giving the golfer as an option to play the hole with success.
So, to answer your question (which seems plain and clear to me), I’m sure there was a variety of par 4’s on ODG courses....some were meant to be reached with a long iron by the average golfer....and they often were designed with an avenue that was accommodating to a low, running shot. If a golfer was wise and understood the hazards and skill level they possessed, they may very well have chosen to take three strikes to reach a green on a long par 4.
