Interesting that you develop your list for a whole month -- that way it gives the patterns some time to emerge. I know I have often seen this, thinking for example, that there have been way too many 40's lately, but then the trend gets even more extreme over a couple of draws.
You are absolutely right Icewynd
The same numbers over the term are designed to capture emerging trends. The Top 20 is projected for an upcoming term of 10 draws.
Lotto 649 draw September 25 2010 - Another ALL SEVEN NUMBERS
The Top Twenty is the only predidiction pool to have ever captured all 7 numbers not just once, not twice but 3 times!!!
