got (something) down to a science
To learn, master, or understand something perfectly, to the point of requiring little or no focus to do, recall, or accomplish it. Once I get my routine down to a science, I know I'll start to feel more comfortable at my new job. I'm a working mom of three, so I've got lunch-making down to a science—I put out all the pieces of bread, add jelly to each one, and then do the same with peanut butter.
