What makes this remarkable in Selby's case is that just three years ago he hadn't even made 30.
It shows his rapid rate of improvement and helps to explain his rise to fourth in the world rankings.
There was some good snooker played on an interesting first day at Crondon Park. An exceptionally tough group sees Joe Perry, winner of CLS last year, bottom of the table but still able to qualify if he has a better day today.
Stephen Hendry took only two points from three matches so will need to win at least two of his remaining three later today.
Ding Junhui particularly impressesd, as did Selby and they seem certain to qualify for the semi-finals.
Well done to Barry Hawkins, whose partner has just given birth. Barry has withdrawn from group 2 on Wednesday and Thursday and will be replaced by Peter Ebdon.
It has been confirmed that John Higgins and Neil Robertson are among the players coming in later in the CLS season.
The players are in good spirits backstage. There's a nice atmosphere and it's all very relaxed, with nobody feeling they have to watch what they have to say as is sometimes the case at main tour events.
Barry Hearn, boss of Matchroom, paid a visit yesterday fresh from the most succcessful PDC World Darts Championship ticket-wise in history.
He had a few words of comfort for Hendry after he lost 3-1 to Ding: "Don't worry, Stephen. At least you came second!"
