Here are the top ten century makers based on all professional tournaments staged so far this season...
1) Ronnie O’Sullivan – 31
2) Mark Selby – 27
3) John Higgins – 25
4) Ding Junhui – 18
5) Ali Carter, Joe Perry - 17
7) Stephen Maguire, Judd Trump – 15
9) Marco Fu, Ricky Walden – 14
Last season, O'Sullivan made 50 in total. He will need a good run in both the China Open and World Championship to reach this figure again.
Selby is just four behind, which gives a lie to the suggestion that he is some sort of grinder, grafting out results by tieing his opponents in knots.
Perhaps more interesting, though, are the players not in the top ten who you may expect to see there.
Shaun Murphy made 24 centuries last season but has compiled only six during the current campaign.
Ryan Day constructed 20 during 2007/08 but has so far made nine this season.
Stephen Hendry, who leads O'Sullivan by 166 at the top of the list, has eight to his name in the current season.
