IE if you search twice as long and every time you double the time, you double the number you get right, that is linear. But if you double the search time and you get 1.2 times more correct answers, _that_ is also linear. Linear is a straight line. It doesn't have to have a slope of 45 degrees.. IE in the "Crafty goes deep" experiment done by Monty Newborn, the number was something like 15% better for each additional ply of depth. That is still a linear curve.
