I don't believe this is a good thing & I'm not a supporter of timing people.
I don't believe shot time has anything to do with entertainment value in and of itself.
I believe that quick players used to be made to look good because they were playing slower players, it was the contrast which highlighted it as a positive.
When two fast players play each other it has the potential to be as tedious as when two slow players play each other, because there's no contrast. We can't rationalise to ourselves why we want A or B to win.
However, when there's a contrast we can say "I want the quick player to win because the other guy is tedious" and we can conversely say "I want the slow player to win because the quick player doesn't give a hoot & is embarrassingly careless".
And there's nothing uglier than when a quick player misses a shot, like everyone will scream at the telly "Dude! Why didn't you just take you time and make SURE of that POT, you IDIOT!"
However, when a slow player misses a shot it doesn't look ugly because they've made the shot appear hard by allowing the viewer to believe its a hard shot, it must have been, he spent that long thinking about it.
There's a hierarchy here, not a black and white:
Most entertaining to least:
Slow, deliberate player vs Quick, impulsive player neither missing
Slow player missing vs quick player not missing
Slow player not missing vs quick player missing
Quick player vs quick player neither missing anything
Slow player vs slow player neither missing anything
Slow player missing vs slow player missing
Quick player missing vs quick player missing
And the important part of the story is the character. I feel sure that snooker fans are not singularly watching snooker in order to watch 2 robots pass round the table hitting balls in a uniform way.
I feel sure that Ebdon vs O'Sullivan or Thorburn vs White will provide much more televisual excitement than Yan Bing Tao vs Jack Lisowski or Steven Maguire vs Barry Hawkins.
I agree with the whole thing about preventing a repeat of the whole Griffiths VS Thorburn or Thorburn vs Charlton type experiences, but I'm not sure pressuring shot-time is the way to go about that.
The 'best' match from the last WC was Wilson vs McGill afterall, and the best frame of that match was the longest frame of the tournament... [mic drop]
