I gather you're saying you can't pick the numbers with certainty but you can generally do better than pure chance.
That's a claim which can be quantifiably tested (and a talent which can win the JREF's million dollar prize if true).
hmm.. well reasonably I'd say why win a million when you can win 130 million. But certainly something I'd take into consideration if the tester would be willing to participate in the practice with me.
The numbers can be picked with certainty after a reasonable amount of practice time is given. To begin with you may be off by a number always, and then off by a number sometimes, and then it becomes a more consistent return. Like... You are off only 8 out of 10 times. Then it becomes more consistent.
Psychically I find it impossible to draw lottery numbers because I have pre existing prejudice concerning it. One becomes more inclined to be more accurate in circumstances where there is no pre existing prejudice. There is a lot of prejudice concerning winning the lottery. This is what the practice times for the lottery winning times are for. The more you get a consistent return the less merit the pre existing prejudice has.
