Hopefully this kills the idea

FIA publishes analysis on medals system. Here's the key piece of analysis.

Fourteen World Championship battles would have been shorter (1955, 1970, 1978, 1987, 1992, 1993, 1994, 1995, 1996, 1997, 2000, 2001, 2003 and 2004).

Eight World Championship battles would have lasted longer (1973, 1977, 1979, 1980, 1990, 1991, 2001 and 2005).

In terms of World Championship final race showdowns, there would have been five lost (1955, 1994, 1996, 1997, 2000) but six gained (1977, 1979, 1980, 1990, 1991 and 2005).

So in other words we would lose several last race showdowns and the championship would have been concluded earlier more times than it would have been extended. So if the idea is to make the season longer it won't work. A stupid stupid idea!
