I would like 20 (of 40) best numbers to play.

Does this software do anything like that after analysing previous draws?

The best and worst numbers are usually the frequency/occurrence within the selected draws(analyze 'Ticket Numbers' or 'Number Combinations'). You would have to then sort the analyzer tables(Occurrence, AVG Interval, or Due etc.), then select and filter the highest/lowest table rows for your strategy.
