Prompted by recent posts from ethanl and AllenB's response thereto (see https://www.lotterypost.com/thread/338583), I started looking at Connecticut's Pick 3 with an eye towards looking to see if doing a similar "Fifths" analysis might offer some benefit. I haven't fully Excel'd this yet, but my spot checks seem to show there might in fact be some benefit. Summarized below is my thought process, offered here for "Peer Review"
Step One: Convert the last 7 draws to "Fifths" as follows:
For each position, I convert to "Fifths" per the table below and then sort low to high as this a Box-type analysis:
0 or 1 converts to a Code 0
2 or 3 converts to a Code 1
4 or 5 converts to a Code 2
6 or 7 converts to a Code 3
8 or 9 converts to a Code 4
==> So the draw range changes from 000 - 999 to 000 - 444
Connecticut's last 7 Pick 3 (Day) draws, through Sunday 10/24/2021, convert as follows:
10/24/2021 782 ==> 341 ==> 134 (Pairs 13, 14, 34)
10/23/2021 159 ==> 024 ==> 024 (Pairs 02, 04, 24)
10/22/2021 841 ==> 420 ==> 024 (Pairs 02, 04, 24)
10/21/2021 873 ==> 431 ==> 134 (Pairs 13, 14, 34)
10/20/2021 765 ==> 332 ==> 233 (Pairs 23, 33, 33)
10/19/2021 588 ==> 244 ==> 244 (Pairs 24, 24, 44)
10/18/2021 543 ==> 221 ==> 122 (Pairs 12, 22, 22)
Step Two: Compile Frequency Listing of Pairs Over Last 7 Draws
The Sorted Frequency List looks like this:
Pair 24 4 Hits
Pair 02 2 Hits
Pair 04 2 Hits
Pair 12 2 Hits
Pair 13 2 Hits
Pair 14 2 Hits
Pair 23 2 Hits
Pair 34 2 Hits
Pair 22 1 Hit
Pair 33 1 Hit
Pair 44 1 Hit
All Others: No Shows
Step Three: Take Top Two From Above, Put Into One String, Sort By Frequency of Digits
24, 02 ==> 2402 ==> 2240
Step Four: Split Above String Into Triplets, Left to Right (With Wraparound at Tail End), Sort Each Low to High:
2240 ==> 224 240 402 022 ==> 224 024 024 022 ==> Strip Duplicates ==> 224 022
Step Five: Keep Strings That Have The Least Inline Digits In Common With Code of Last Draw
Last Code 134
224 ==> 1 Inline Digits In Common (Bolded)
022 ==> 0 Inline Digits In Common
==> Select 022
Step 6: Convert Selected Code Back to "Normal":
022 ==> Position 1 (0,1) Position 2 (4,5) Position 3 (4,5)
==> 044 045 054 055 144 145 154 155 ==> 044 045 055 144 145 155
Step 7: Keep Numbers That Have No More Than Two Digits In Common With Previous Draw
Previous Draw: 782 ==> Keep All ==> 044 045 055 144 145 155
Step 8: Play List For Next 7 Days
