Aiming and tapping not match

Here is my problem, I often mess up jumps, but when I use rewind to see if my aim is the problem, it appears that I actually aim at the circle. But the thing is the moment I get my cursor onto the circle, i don't tap it. It is only until my cursor slightly move away to reach the other circle, I start to tap the circle that my cursor is moving away from. This happens very frequently and I still can't find anyway to fix it. What is it called and what can I do about it? I will include a rewind of what it looks like
