There's been a lot of talk about Abu Dhabi and double points but relatively little discussion of the underlying points system that got us to this point.
Over the years a number of systems have been used; for brevity I'll just list the points for 1st, 2nd, 3rd. The most significant factor is the value of a 2nd place finish relative to 1st so I'll call that out as well, along with where we would be in this year's championship and what Hamilton would need to do to win in AD (assuming NR wins the race and ignoring double points). In chronological order:
1950-1960: 8-6-4 (2nd worth 75% of 1st); LH 113-108 NR (Hamilton would need 3rd - 1 point for fastest lap)
1961-1990: 9-6-4 (2nd worth 67%
