"I tried to work on my ball striking a little bit. I obviously didn't have a lot of time coming into this week. I wish I had like a month plus to make sure that my whole game is there.
"I felt like we were moving in the right direction, but I was talking to [coach] Sean [Foley], and he said 'just be patient out there'. I think that's going to be a big key."
Despite Lake Nona being her home course, Ko believed her opening round was the best she'd played on what was a challenging set of holes.
"Hands down. I think this is probably my best score around here.
"But I think it's a pretty tricky golf course and the greens are subtle in some areas. I think that makes it extra tricky."
Ko's drought without a victory, which she went close to breaking last year in finishing runner-up at the Marathon Classic in Ohio, will be three years in April.
But with today's impressive opening round, her chances of breaking that drought have been significantly raised.
