FORM USAGE

RATING TYPE The rating system can be altered in two ways. The system is pre-set to find the best combinations. You can also find the worst ball numbers by inverting the rating value, should you feel these are more likely to appear in the future. The standard procedure requires the JavaScript Math package. Most platforms now support this, but if errors occur due to an unknown function 'Exp', you should revert to the alternative procedure by clicking it's checkbox.   COLLATION You can modify the draws used when considering the past appearances of balls by selecting options from this section. To alter the draw numbers used, type the range into the text boxes or click one of the preset value buttons. The program automatically excludes the bonus ball from the appearances list. De-click the check-box below to include it in the search.   TOP 20 COMBS This will calculate the best rated 3,4,5 or 6 ball combinations using data from the draw numbers selected in the Collation form. The depth of the search will determine how thorough the search is and therefore how long it will take. Try not to enter too high a value -   6.0 will check nearly all 1225 pairs, but a value of  2.5 will come up with the top20 3 ball combs, correct to about 19 places, in a far quicker time. The longer the combination length, the higher the value you may need to take   -   for reasonable depth and time try 3.2 The process of finding the best 20 combinations takes three main stages. Firstly, the data for the draws specified is collated (but only if this has not been done already). Then a list of pairs is calculated - a long process which is not repeated for varying combination lengths. The final process is to compute the actual combinations themselves. The algorithm checks the 'better' pairs first and since these take longer to compute, the status bar will 'count down' more quickly further on in the process. The prediction scheme can be ignored, or selected in one of two ways. "Predict, then find" adds the prediction rating whilst pairing the balls, so only predicted pairs will be searched. "Find, then predict" finds the top 20 combinations first and then adds on the prediction values for those found. So all 'good' pairs are searched, but the actual rating values for the top 20 will not be in numerical order.
