Hi Bloubul,
The Davinci Matrix is a graphical representation of draw frequencies for each number over the past 52 drawings. What you will get is a kind of sideways bell curve with the most numbers appearing around 6, 7, or 8 hits in 52 draws. The theory is that there are areas of the chart from which numbers are more likely to be drawn. It produces some hits, say an average of 3-5 out of 6 (occasionally all of them) but that is because there are generally 25 or so numbers in the 'hot' area of the chart.
A google search for "davinci matrix lotto" will find the information you are seeking.
