Without a point for FL;
Prost has 2470.5 points (5th all-time in points, up from 17th). Here is the thing though, if you used both the current points system and the current championship system, Prost is potentially the greatest of all-time, surpassing Fangio and becoming a 7-time world champion. He wins 4 in a row from 1983-1986, back-to-back in 1988 and 1989 and then his final one in 1993. In this stretch, Piquet ('83), Lauda ('84) and Senna ('89) all lose a WDC to him. In '83 he would have finished level on points with Piquet, winning the championship on wins count back (4 to 3).
Senna has 1859.5 points (8th all-time, up from 20th).
Schumacher has 3890 points (2nd all-time in points, up from 9th). The 'What-If' scenarios here are he loses the '94 title to Hill who still doesn't need to take a risk at Adelaide (16-point lead heading into the final race means Hill just needed to finish inside the top-4 to secure the title), but he beats Villeneuve in 1997 because he would've only needed to have finished 7th or higher in the final race to win the championship (22-point lead heading into Jerez).
