Consecutive rounds of 71 over the weekend doomed Ko to a tie for fifth on the leaderboard after a hot start to the tournament.
"I feel like I wasn't able to get things going over this weekend. Overall I played really solid. Even the last couple days, I hit a couple of not-so-good shots, but other than that... I feel like there were a lot of good things, and like I said, sometimes when you get in a good rhythm of things, you're able to keep it going," Ko told media following her round.
"But I just was never on that train on this weekend, hopefully this is a good momentum for next week."
Next week for Ko is a shot at the Women's British Open, a tournament in which she's traditionally struggled to make a mark in. However, the fact it's taking place at a brand new venue in 2022 has given her hope for a better result.
"Yeah, I haven't had the greatest I think track record at The Open. So I'm excited for Muirfield. Obviously it's the first time that the women's championship is there, so it's a pretty historic venue and historic championship.
"I've heard a lot of great things about it. Seen it on TV. So I'm excited to go play."
Fifth place at Dundonald this weekend earned Ko a purse of NZ$99,101 to take her 2022 earnings to just under NZ$2.5m.
