In 2017 I went from 48kg to 60kg for the bent press. I almost always did it before my other lifting, so it was mostly a warm-up.
I made it very simple. I picked 6 weights: 16, 24, 32, 40, and 48. I assigned each one a number 1-6, with 32 getting two numbers, 3 & 4. Each number corresponds to the numbers on a six-sided die. I would roll the die each day and use the specified bell based on the number I rolled. 1 got 5 reps, 2 got 4 reps, 3 & 4 got 3 reps, 5 got 2 reps, and 6 got one rep. Over time I’d try to increase by one rep whenever I felt comfortable doing so. By October I was able to do 48 x 3 for two sets. Then in November I made 60kg.
I did the exact same protocol for the Turkish get-up and also achieved 60kg, but with a human, not a kettlebell.
