I looked into whether the Friday or Sat & Sun pin positions performed better. There weren't enough rounds to do my usual calculations so I used scoring spread and the average departure from expected score (where expected score is the linear fit of hole scores to total score for the round).
A wider scoring spread is better (more different scores to different players).
But, for each player, a better hole should give out fewer different scores, or at least not give out wildly different scores.
On this chart, that means up and right are "better". This shows just the holes that were changed from the Friday layout (F) to the Sat & Sun layout (S).
Holes 6, and 9 were better in both aspects on the Sat & Sun layout. They had both wider scoring spreads among all players, and smaller departures from expected scores.
Hole 14 widened the scoring spread at the cost of more departures from expected. However, the extra departures were less than what would be expected for the extra scoring spread, so it may have been a good move overall.
Holes 4, 5, and 11 were not much changed.
Holes 1, 2, and 18 merely made a trade-off of more scoring spread for a typical degree of more departures. However, note that the two ways for a hole to be bad are to have too little scoring spread or too many departures from expected. Since holes 1 and 18 are out there on the bad edges, we would prefer hole 1 to use the position with the wider scoring spread, and hole 18 to use the position with the smaller departures from expected.
So, hole 18 is the only one where the Friday position performed better. For Holes 1, 6, 9, and 14 the Sat & Sun position worked better, and the rest were a wash.
