In your opinion, whar is the maximum number of charts that should be run on a singlr issue test? If the person taking the test scores .99 deceptive on the first three charts, and multiple charts are given after that, can any finding after that be valid? After 12 charts, the examiner went from deceptive to inconclusive.
Am I correct in assuming that this is improper procedure.

A little more info would help. a single issue test, for example "did you shoot John" would normally with most techniques take three charts to render an opinion.
Were you asked the exact same questions on all 12 charts? I think that most examiners would agree with me that 12 charts is to many at one time.
If the results were showing deception after three charts were admissions made that would change the questions? In other words did the examiner, due to something he was told after the first 3 charts change the questions to include that information? For example did he change a question or questions to something like "Besides what you told me were you involved in the shooting of John"? Something like that might cause the examiner to keep running charts and he might even get to a point where he said "at this point I can no longer say if the subject is being truthful or deceptive to the questions now being asked".
I hope that helps, if not give more information. Such as were the questions changed or amended in any way or were completly different questions asked after the first three charts.
