In mine, Eisenhower was the most attuned to playing often.
Nixon I think picked up the game as his VP. Nixon was also denied membership in Balthusal CC while BP interestingly.
Clinton I think played golf more for the party atmosphere. He and Norman were remored philanderers after their rounds together.
JFK was a good golfer but his back did not allow for much playing (golf) was president.
Bush I probably played more round than did W over their two terms for sure but neither ever played a round for more than 4 hours as they played quickly.
Ford was perhaps one of the better golfers of the bunch but his wildness off tee was dwelled upon by the press.
But as you say, with the exception of Eisenhower, I don’t think if you added all the rounds played by all the golfing presidents since Ike, they would not equal the number played by Obama.
IIRC, Eisenhower had a putting green put in at the White House, Clinton had the first hot tub put in the White House.
