The collation form allows you to select which draws you want to analyse.

First select the range of draws you want to use. Use one of the predefined ranges or customise your own by typing the first and last draw numbers into the text boxes provided.
Next choose which machine and/or set-of-balls you wish to analyse the results of. Don't forget, the program will only use results from the range of draws you have chosen.
You can also include or exclude the bonus ball from the statistics.
