Because it is a training device to help you learn where to put the CB. Once you get the feel for things, you don't need it anymore or only when you are having trouble with a certain shot. It the best training device for beginning players and for those having trouble with certain shots.
You need to read better. That drawing shows that no matter where the CB is on the table, the spot on the table that represents the GB contact patch is always the same. It shows two circles that represents possible CB locations on the table.
Those lines are direction of travel lines that represents the path the CB takes when hit.
There was also a write up that went with it that explained all this but I guess you didn't see that one. Go find them if want to. The orginal thread was title My GB Journey.
As stated, if you do something long enough, it becomes natural, second nature, a reaction that requires no thought. Those that still use any form of a system are stuck. Shot making is not natural to them because they have not spent enough time at the table for shot making to become natural.
As example, I practice 2-3 hours every other day, with at least one 6-7 hour session once a month. I might take weekends off once in awhile. This is on 9ft table with tight pockets. Now when I practice, I mean throwing the 15 balls out there and going to town. Thats 2-3hours at the table hitting balls. Thats 2-3 hours straight, non stop, seldom sitting down for breaks and on so. I've been doing this practice schedule now for 2 years. This is how the pros got to be pros.
Anyone else this committed to practice? I doubt it becuase there have been way to many statements like "since I can't practice enough I use xxx system" or "using xxx system you don't to spend so much time hitting balls".
These types of statements show nothing more than how limited a view these people have about running balls.
This forum is really a small part of the pool world. Where I play, none know of this site or even heard of CTE .
I learned by hitting balls. I picked up a stick, put the balls on the table and had at it. I played for three years before I ever found out about Mosconis book or even knew they were books on play out there. This was way back in the later 60's, early 70's when the internet was not around. That right kiddies, there was a time before the internet. It also was a very small town where the tables were in the rec center. There were no pool halls there and still aren't any today. Needless to say, but I will any way, reading Mosconis book only confirmed what I had learn already.
And who really cares about a video of you making shots or anyone for that matter. Anyone that posts this kinda stuff is just trying to show off, be a big man, "See look at what I can do" when most are thinking yeah well so what I can do that too and even better shots.
FWIW
If you need a "training device" to help you learn where to hit the cue ball then you aren't doing it naturally. You aren't feeling it you are measuring it using a preset device to train you to see the distance.
Nice try on your snide remark about me video taping myself. I made a video of myself playing so I could test my camera setup. I really have to wonder about people who try so hard to put others down by acting like amateur psychologists. You just had to gloss over the POINT I was making which is that my playing looks "natural" even though I am using a system to aim.
As to the idea that a system can't help a person avoid practice you are dead wrong.
I guarantee you I don't have to play 2-3 hours a day to be in top form. Not anywhere close. I am not trying to be a pro either but I am sure you don't have to like it if we match up. I say that based on what I know of my own game and my own ability to put 2-3 packs together at any time if I am in stroke.
I know FOR SURE with a million percent certainty that using CTE allows me to make shots that I have NEVER EVER NOT ONCE in my life practiced before. Shots that I normally wouldn't even think to attempt because I never shot them before. If that's not a "shortcut" then I don't know what is.
Now you can discount the "system" and call me delusional or whatever. But my stats are that I have run 98 in straight pool, more 8 and outs than I can count, 5 racks of 9 ball, 5 racks of 8 ball, 2 racks of rotation, and 15 banks in a row. I think I am cognizant enough of my own ability to know when I am making shots using a certain method that are technically "over my head".
The only time in my life that I ever played on the natural - that is with no instruction was from 12-14. That's when I played at Johnny's gameroom in OKC and no one taught me anything. I won games from the Mexicans for $1 a game and ususally went home with $20 in winnings.
Until the day the Indian kid showed up and beat me out of the grocery money Mom had given me. Found out he played at a place called Trueloves Pool Room. It was a bit before I got to Trueloves but before that I rode my bike to a Korean pool room and discovered 9ft pool tables and 10 foot carom tables. That's where I first saw real players. The indian kid was a real player too but I didn't know it when he was beating me. The big tables looked like football fields.
So that's when I started actually learning how to PLAY not just bang the balls around.
And that was before the internet as well. So don't patronize me with your "experience". I am sure that mine equals or exceeds yours when it comes to who has been around.
