Good conversation, Dunn.
Per the above, I guess I'm not seeing it...I don't understand how the information is useful.

Likewise DD,
I'll try to help you get a clearer understanding. First you are too focused. That in itself is normally good, but we need to take a step back to look at the bigger picture.
I don't receive this feedback all the time,..... ie: its not always there,so when it happens and you feel it ,... its golden.

Tramp uses the example of a miscue because it is blatant. You'll "feel" that miscue all along the cue. Lets say you miss-stroke a shot. You are going to feel the lack of uniformity in your stroke. It is very slight, but there none the less, you need to be attuned to it.
What does it tell me?? Well it tells me the obvious, I'm going to miss the shot probably. How does that have value?? In the present tense of just making the shot, nothing ! (as stated before all I can do is watch). Here is the value: Ask yourself, "should I take a shot like that again in the match??"
"Was it my stroke,.. or a table condition??"
Lets FLIP this : you see your opp take a shot and hear/notice the hit is not right. Given the chance, will you leave them a similar shot to make? (I would).
Here's another, Your opp makes a solid hit on a long almost in-line rail shot. the CB stops and squats right within 1/2 inch of contact with the OB. (you knew he had to give it a lil english in order to get pocket-point). You gonna leave him this shot again in the match ??? (nope!).
Look at it this way:
Google(and others) store Petabytes of information in huge "server-farms"[There are two that are known; one is in WA. State, the other recently built in the mid-west] Google didn't spend the $$$$ on the equipment needed to do this because they like trivial information! A million purchases on Amazon doesn't tell them much, BUT a million purchases on Amazon by women age 30-55 on the Monday after Thanksgiving tells them everything.
DD, I hope this helped, I don't know how else to explain it.
