Within the lottery forecasting industry there has been a great deal of attention paid to lottery balls. A tremendous amount of effort and study has been focused on the relationship between the microscopically differing physical attributes of the individual lottery balls and the frequency of their appearance rates.

Many lottery prediction professionals adhere to a school of thought that a greater accuracy of lotto number forecasting can occur if a devotee of the game has a developed knowledge of a draw history database indicating which ball sets were used in which particular lottery draw.

This belief that a relationship exists between the variations of ball weight, density, mass, colour and shapes manifests itself in theories which suggest that a minimum lottery draw history of at least 60 draws, after a new set of balls have been introduced, must be studied for predictive relationships to be effective.

The supposedly new pattern or lottery signature, based upon the miniscule physical variances between the lotto balls will emerge after this time. The belief in this factor of lottery prediction is so significant that many lottery analysis software and program development designers actually place functions within their software applications to track and analyze the ball sets and dates on which those particular balls appeared for those particular draws.
