In my experience, dragging the scrollbar slowly hasn't been an issue I've seen. What I have seen people do is drag the scrollbar really quickly and end up at the bottom of the page, when what they want is in the middle. They correct this by dragging the scrollbar sharply up, but they're now back at the top of the page. Rince, repeat. I also see people use the arrow buttons on the scrollbar. But they just click the button repeatedly instead of holding it down. Which means that for a very long page, it can take them a long time and hundreds of clicks to get to the section of the page they want to see.
