Here's what you need to do. The sweet scent advances the frame by 2 frame points when you're using to find a wild pokemon in the grass/cave.
So in order to hit your target frame, you need to stop advancing the frame at the number that is two frames lower.
Like for example - if your target frame to catch a wild pokemon is 32, you need stop advancing the frame at 30 and then use sweet scent to advance the frame by 2.
It's like doing a math problem at school. 30 + 2 = 32
Do you understand?
