Harrah's is no different than Lipscomb at the WPT. They want those final tables to end in under eight hours. No overtime for the film crew.
Slower blind structure would offer more play. Better for the players and spectators. But risk running over eight hours.
Very few finals are played at a faster rate then 25 deals per hour. The ingrained culture of poker says players aren't to call the clock on slow players. You can't have it both ways. Either play faster or expect blind levels to move up quickly. Those film crews will be out in under eight hours.
