Here is a quote from the article:
To account for Google Instant, comScore has again changed methodology. “Explicit core search” essentially backs out Instant and only records a search when the user clicks a link or presses the enter button. “Core search” also records a search when users pause for 3 seconds to contemplate suggested Instant results.
So a 3 second pause counts as an additional search. I wonder if that could have skewed the numbers in Google's favor.
