Unfortunately I did not wheel enough combinations to get any 5/6 or 6/6 match. What is your top 20 number selection strategy? It would be good to apply it to other, lower cost lotteries so that the total cost will be less and enough wheel combinations can be played to get 5/6+ match.
The Top 20 numbers are selected from a cross section of hot and cold numbers with attention to sum and other factors. They are a set targeted at hooking into an upcoming trend in the 649 draw results. The micro details of the selection process are secret
Your point about the practical possibility for a player to wheel that amount of numbers is right on. The set is way too large.
The purpose of the Top 20 is to capture a significant number of winners within a set that is much less than half of the total 49.
While 20 is too many for a single player to cover that disadvantage is offset by the number of players using the set.
Tons of players follow and use the Top 20 since 1999 and when the set contains winners, especially all 7 then someone is cashing in big!
Here is a list of dates when the Top 20 have predicted all 7.

I hope someday you lock into all seven simply by picking the right ones out of the 20 pool.
