Some more stats on comparing the Pole Position lap time to the Fastest
Race lap time (ignoring practice sessions which didn't count towards
qualifying).
There have been 883 World Championship races:
In 788 (89%) the pole position time was quicker than the race FL
In 91 (10%) the race fastest lap time was quicker than the PP time
In 4 (0.45%) the two times were exactly the same
Dealing with the latter 4 first:
Germany 1951 - 9'55.8s Ascari (PP), Fangio (FL)
Britain 1955 - 2'00.4s Moss (both)
Pescara 1957 - 9'44.6s Fangio (PP), Moss (FL)
Italy 1967 - 1'28.5s Clark (both)
All of those were hand-timed to the nearest tenth.
I want to take a closer look at the 91 races where the fastest lap was
quicker than the PP time. Clearly in many cases the weather will usually
have interfered with qualifying. In the meantime here is a count per
decade:
1950s 17 (includes one Indy 500, in 1955)
1960s 17
1970s 9
1980s 0
1990s 7
2000s 36 (includes 6 GPs in 2005 when PP was decided on aggregate)
2010s 5
The 5 since 2009 are:
Malaysia 2010 Mark Webber (both) FL 12s quicker
Brazil 2010 Hulkenberg/Hamilton FL 0.6s
Britain 2012 Alonso/Räikkönen FL 17s
Germany 2012 Alonso/Schumacher FL 21s
Malaysia 2013 Vettel/Perez FL 10s
In the 788 races where PP was quicker, the all-time average difference
is ~3.5s, or about 3.7%. The figures per year for the current Pirelli
era are:
2011 4.2s 4.9%
2012 4.0s 4.5%
2013 3.5s 4.1% (only 4 races counted)
For comparison these are the figures for 2001-10:
2001 2.8s 3.4% Bridgestone/Michelin
2002 2.9s 3.6% " "
2003 1.6s 2.0% " "
2004 0.9s 1.2% " "
2005 1.3s 1.5% " "
2006 1.7s 2.1% " "
2007 1.2s 1.4% Bridgestone
2008 1.4s 1.7% "
2009 2.2s 2.3% "
2010 3.6s 4.0% "
Non-emergency tyre changes were banned in 2005, but reinstated in 2006.
Up to 2008 tyres were grooved with slicks returning in 2009.
Two two compounds per race rule was introduced in 2007.
