 By resetting and compressing the scoring of the top 10 (later 12, then 16) drivers, the chances of each of those drivers winning the championship was increased, while not precluding anyone with a legitimate chance of winning.The original choice of top 10 drivers was based on the historical analysis that no driver outside the top 10, with 10 races remaining in the season, had ever gone on to win the Championship.The expansion to top 16 in 2014 made the elimination rounds possible.
