Modified Stableford (Barracuda)

Eagle +5
Birdie +2
Par 0
Bogey -1
Double or worse -3

Ignoring player specific attributes, does it help the better players more than normal?

I would posit that it helps higher variance players more than better golfers.

Reading about the Mark Baldwin last year, it does seem to change the player’s course strategy given the importance of eagles to the overall score.

Looking at Pendrith - he is 2 under par in strokeplay but only got 5 points because he had 4 birdies and one double bogey.

Highsmith is level par but got 7 points because he got an eagle along the way offset by a double bogey and five birdies and five bogeys.

Higher variance within a round is rewarded more by the scoring system.
