I just dont see what is the big deal about waiting til the end of the rack to see the score. Are you just watching now and then for some reason with no sound?
Its the biggest deal to me, and annoys me to no end. Its worse than when the commentators go off on tangents and start singing songs.
Imagine watching a football game when the score is only shown after a touchdown. You will quickly forget what the score is, and lose interest.
To answer your question, I both do watch intently for some periods of time, and other periods of time I shift my focus and have it on in the background on the TV. In either case, if a rack takes 10 minutes (which due to the racking BS in this tournament they all took about that long), and the score is only shown for 15 seconds every 10 minutes, well, thats a very small window to see the score.
Its not an unreasonable request. Almost every single sporting event on network TV constantly shows the score. I remember in the 80's the football games did not show it all the time. Then, one of the networks, maybe Fox in the 90's, came up with their scoreboard that was always on, across the top row of the screen. Shortly thereafter, every other network that broadcast football came up with a similar scoreboard that is constantly shown.
These network pros know what they are doing. Pool should copy as much as they can from network TV. What I'm asking for costs zero money, has no disadvantages, and may potentially keep viewers more interested.
