In most seasons until 1990, only a certain number of a driver's best results were counted towards the World Championship. This made a difference to the outcome in, when McLaren drivers Ayrton Senna and Alain Prost finished first and second respectively. Prost finished 14 races in either first or second, retiring from the other two, while Senna won 8 races to Prost's 7, meaning that he only needed 3 further 2nd places to secure the championship irrespective of Prost's other results. Senna succeeded in doing this and became champion, although Prost would have scored more points had all the races counted. In 1964John Surtees became champion ahead of Graham Hill for the similar reason. When the Constructors' Championship was introduced in 1958, points were only awarded to each constructor for its single best-finishing driver in a points-scoring position. This was the case until the change introduced before the season saw a constructor's points total now being the accumulation of all points scored by the constructor's drivers: by this time, constructors were mostly running two-car teams and privateer entries had almost disappeared. A new system counting the points from all races was introduced in, along with an extra point being awarded to the winner of a race, for the total of 26 points awarded per race. In 2003, the FIA inflated the points system by 50%: to distribute 39 points per race between the first eight places instead of 24–26 points between the first five or six places along with a point for an occasional fastest lap, as had been the case since the inception of the championship. The FIA changed the scoring system again in 2010, this time inflating the points system by more than 150%, and extending it to the first ten places. 102 points are currently being distributed every race, with 25 being awarded to the race winner. In 2014, double points were awarded for the final race of the season to make it less likely that one dominant manufacturer or driver would build up an unassailable lead with several races still left, as had happened the year before. Double points have not been used again since. The most dominant Drivers' Champion in terms of points scored is Jim Clark, who scored the maximum of 54 points in both and. In recent times, Michael Schumacher finished on the podium in every race of the season to score 144 of a maximum 170 points. The most dominant Constructors' Champion in recent times was McLaren in, scoring 199 of a maximum 240 points and finishing 134 points ahead of its nearest rival. In, Ferrari scored 221 points, as many as all the other teams combined. Throughout history, bonus points have never been awarded for led laps or pole positions, as was common in other racing series like IndyCar or most Touring Car championships.
