I've created a bit of a 'hack'. I suppose that is what I should call it - it's such a buzz word these days - everyone has a hack.
Anyway, all I have done is created a 7 number lotto from 50 balls for our powerball game which is 6 from 40 plus powerball which is 1 from 10. For EL I have added 40 to the previously drawn powerballs - 1 becomes 41 etc.
My starting package is 7 from 50 and reduced by using a number group to have 1 number from 41 to 50 required which reduces my package to the combinations for a 6 from 40 lottery with 1 from 10 powerball.
It won't be perfect for a lot of filters but will be useful to use with many of them.
Might be taking naps between filtering though.
