First, the clickable area is much larger than the displayed progress bar so you don't have to be that exact.
Second, you can also display a clickable waveform of the playing track with a configurable height.
Preferences > Layout (1) > Arrange Panels
Drag the wavebar to one of the areas on the left.
Depending on which skin you use, I think it's also an option by right-clicking the existing progress bar.
Bee excellent to each other...
