I made a slightly different dtaabase on the doubles with my software. I used a constant "0" plus the 2 digits in the double. There will always be at least 1 digit repeat from entry to entry. When the "0" is one of the two digits it will show a 2 digit repeat.
The new database is indicating only a 1 digit repeat which would be the constant '0". This means the last two digits (0 amd 4) should not be involved in the next double.
It is indicating that 1 digit five plus games out to be involved. This database also has a constant code for 1 of the two needed.
The only time there will be a Double in this database is when the "0" is one of the digits in the Double that draws. Therefore I can expect 3 different digits most of the time. Setting filters for a 2/1 on the Levels, the one constant code and using the only 2nd code that gives me results, it is giving 031 and 037 as the numbers probable in the next Doubles draw.
It doesn't indicate which one of them will double though. Just that these digits will probably show up.
Looking at the Repeat Rate for Doubles in the regular database, out of the last 47 Double draws there has been a repeat 22 times. This is close to a 50% repeat rate.
I looked at the Database again and there was actually a 2nd Code that produced possibles. They are 3-2, 3-6 and 8-5 Of those I would lean toward the 8-5 simply because it has an Odd digit in the 3rd position higher then the 4.
Time will tell if this method is able to cut down the possibles or not as for the next draw there seems to be only 5 different combinations.
