Lets take a look into a code number.
the 834 hit mid today code 523
the 492 hit eve today code 352

in the code 235 there are 6 lottery digits . 2 lottery digits in each code number.

code 2 lot #s 2-3
code 3 lot #s 4-5
code 5 lot #s 8-9

gives us lottery #s 235___248-249-258-259-348-349-358-359

so we had the lottery number 4 return to the eve draw. without a 2 return from mid-day would have left the probability of the 2 and 9 hitting keeping the lottery number 4. If I had chosen the lottery number 4 for a return the only probability that could happen would be the 249 lottery combo if the 235 code reapeated.

HMMM got to think about this one a little bit.
