Nope you don't. That is purely a subjective speculation, ie myth that contact induced throw happens on every shot.
Subjective speculation, huh?]
:yikes:]
I have never adjusted for contact induced throw. I do for side spin.
Maybe not consciously...[/COLOR]
There has been no proof that CIT happens on every shot in pool. There have been demonstrations that show CIT can happen under limited set of parameters.
You can't be serious!
I believe those demonstrations are at a CB ball speed that I seldom if ever use. Seldom is there a quantifiable number given to the CB ball speed. It seems to be that CB speed is always defined as fast, medium or slow.
There have been several attempts at making standardized measurements for cueball speed (The Beards books, PAT tests etc). The problem is that most pool players dont' want to consciously think about these things, as there are plenty of other things to think about while playing.
Seldom is it stated the the CB is traveling x ....per ......
It is because nobody has a radar gun with them while playing pool and it is too difficult to measure length/time with the naked eye while playing. Therefore measurements are by result (total distance travelled).
When there is a speed indicated, it has been a speed that I never use. When you do read of a speed, it is in MPH which really isn't a good scale of measurement to use since the playing surface is measured in feet or inches, so a good scale would be x inches per second or x ft per second. This fits into the reality of the world of pool and not mile per hour.
Lets just take a CB speed of 1 MPH. Do you really know how fast that it is on a pool table? What a CB traveling a 1 mph looks like and what type of hit it takes to do it?
Again, this is great for a physics textbook, but unnecessary for playing.
Converting a CB speed of 1 MPH to IPS...inches per second results in 17.6 inches CB speed. Half a pool table is 24 inches. How far apart are the diamonds on the rail?
Just something to think about.
In motorcycle riding there are two ways to turn a bike and at all depends on what speed the bike is going on which style is used. Below x speed, to go right, you turn the bars right and go right. Above x speed, to go right, you first turn the bars left, then the bike leans right for a right turn....its called countersteering. I believe the same thing occurs with CIT, it can occur at a certain point. I just operate at a area of speed below that point CIT occurs.
I'm sorry to disappoint you but CIT occurs at slow speeds as well. It is easily verifiable by setting up a line of balls, like Byrne outlines in his books. The one thing I will say is that CIT is less noticable on cut angles below approximately 20 degrees.
I really posted the link to show someone with far superior credentials than CJ has in a game, 14.1, that is tougher to master than 9 ball has to share about aiming.
That was the request.
PS, this a good example of providing support for ones premise, which is lacking in your reply.
I suggest you and others get this book to really see how weak most arguments on here are.
Making good rational arguments are always nice. In the case of contact induced throw you can easily verify the existence of it yourself, with no other instruments needed than your eyes, poolballs and a table. You can't argue away the results you get when actually applying the methods Byrne and others have shown us.
