What I mean is if you get a morning pairing thurs and it is dead calm, then the a gale force wind hits in the afternoon after you've finished, and continues until your afternoon teetime on friday, then ceases. This has happened numerous times at the Open where luck in tee time draw is a huge factor. Obviously the people that had an afternoon thurs/fri morning tee time are far less likely to make the cut.
This is dead on the money. Take a look at the 2010 Open Championship at St. Andrews. Rory McIlroy shot a 63 in Round 1 when conditions were favourable to almost everyone that day, with eventual champion Louis Oosthuizen shooting a 65.
In Round 2 Louis Oosthuizen shot a 67 with a morning tee time and Rory McIlroy, with an afternoon tee time, shot 80, when winds were over 40mph and play was even suspended for just over an hour.
I'm not saying that McIlroy would have matches Oosthuizen at the top of the leaderboard after Round 2, but merely pointing out that luck just wasn't on his side in round 2, which gave him no chance of winning The Open.
McIlroy finished tied 3rd, 8 shots behind Oosthuizen, a pretty good finish based on his misfortune of tee time in Round 2 where 13 shots were the different between them.
