FYI hard working webmasters.
Google has been disabling natural page scroll of late. Try scrolling SER pages using your keyboard arrow keys and see what i mean.... natural scroll has been replaced by a little pointer jumping from one result to the next, starting at result 1 (which is normally an ad).
Not only they've pushed the organic results down as far as they possibly can (plastering the top fold with ads and google own services), they also make it quite annoying to try and scroll down to them when/if using the keyboard arrow keys (done on laptops alot!)...
