A double digit bias is a lotto trend to look for in the
Odd/Even Bias Tracker Chart
in Advantage Plus.
A double digit bias is when there are 2 lotto numbers of equal probability, but one
is odd and the other is even and the past ten games produced an E=+10, or a
different double digit difference, you would choose the odd number because the
bias would favor the off number being drawn.
