I DID A BRIEF calculation of the total numbers for 12345 pattern 2,3. 6,435x9=57,915x9 (megaballs)... There would be about 521,235 numbers BEFORE they are reduced by additional filters (Can be reduced under 100,000). Thus, when ever pattern 2,3 hits, the winning Megamillion winner will be in that mix when the first number in the winner is between 1-9 and megaball is between 1-9. It would be 1.4 Million to include all 25 mega balls. THEREFORE, the strategy is to keep the numbers in play each week as 2,3 pattern often repeats and to play multiple patterns in a lotto club.
There are 5 12345 patterns that win the most. Thus, 521,235x5=2.6M numbers that would produce back to back Magamillion wins whenever the winning number and megaball number start with numbers from 1-9. This is BEFORE other filters reduce that 2.6M number.
