Okay. Here I will come with such corrections
I'm focusing on the hard/carpet tournaments in the fall
. According to Wikipedia (swedish) and ITF I conclude that:
1976-1980 and 1989-1994: Indoor Carpet
1981-1988 and 1995-2011: Indoor Hard
Which means that 1976-1979, 1995 and 2000-2005 are wrong on ATP, I think.
. According to Wikipedia (english) and ITF I conclude that:
1995-1999 and 2004-2007: Indoor Carpet
2000-2003 and 2008-2011: Indoor Hard
Which means that 2000-2003 are wrong.
. According to ITF and Wikipedia (english)
1968-1970, 1980, 1986-2006: Indoor Carpet
1971: Indoor Clay
1972-1979, 1981-1982, 2007-2011: Indoor Hard
Which means that 2006 are wrong on ATP (not hard). (They are incredibly right otherwise, it seems)
Ho Chi Minh City 2005
. All sources confirmes carpet as surface. ATP is right!
This is according to ITF:
1977-1979, 1981-1986, 1988-1989, 1997, 1999-2006: Indoor Carpet
1987, 1990-1996, 1998, 2007-2011: Indoor Hard [Fr. Wikipedia says 2007-08 is carpet]
1975-1977, 1997, 1999-2006: Indoor Carpet
1978-1996, 1998, 2007-2011: Indoor Hard
If you think ITF is more trustworthy (I doubt so) you have lots of correction to do!
But 1990-2011 they agree
-2006: Indoor Carpet
2007-2011: Indoor Hard
According to ATP and engl. Wikipedia they changed surface two years earlier. I think ITF is wrong on this one, but I'm not sure.
To be continued...
