I worked out that 1964, 1976, 1983, 1984, 1988, 1994, 1997 and 1999 would have a different champion under 2010 scoring. It would mean that Graham Hill would be a triple champion, Lauda would win 76 instead of 84, Prost would be a 7 times world champion (83 by no. of wins, 84 and 88), Damon Hill would be a double champion, Schumacher would win 97 over 94 (He would have a 22 point lead into Jerez 97, so no need to crash) and Irvine would win in 99. Losers would be Surtees in 64, Hunt in 76 and Senna in 88.
