It can be pretty simple today if Rory McIlroy can win the DP World Tour Championship for a fourth time he'll also win an eighth Race To Dubai and tie Colin Montgomerie's record.

McIlroy can also finish top of the rankings with an outright second place in Dubai today - as long as Chacarra doesn't win the tournament.

Technically McIlroy could finish as low as fourth but Chacarra would have to drop right off and finish way down in two-way tie for 46th for that to be enough, and the Spaniard surely won't suffer that sort of collapse.
