Is "World No. 1" Status Enhanced Or Diminished By Recent Revolving Door?

Brooks Koepka won the limited-field CJ Cup Sunday in Korea and while no one noticed in the United States due to interest in many other sports not named golf, I do wonder if Brooks Koepka’s move atop the Official World Golf Ranking is impacted by the recent changes at the top.

As Dan Kilbridge at Golfweek notes, Koepka is still very much grinding to bring his major championship consistency to regular PGA Tour events and is proud of the honor. But given that Dustin Johnson and Justin Rose (ever briefly but long enough to cash some bonuses), held the title of No. 1 in recent weeks, does that lessen the impact of the achievement or speak to unprecedented parity and therefore the difficulty of reaching the top ranking?
