I think the way I am looking at strings ....at least for P3 may be different.
For example... using the draws just up there to demo part of the idea. Notice just the first position each draw up until Wed 7/1/98
I would say there is an ongoing String right there .....just in first position each day. Look..... every single draw had a LOW digit in its last spot for 10 straight draws ..... before it finally Stopped ..and went high digit on the end..... Wednesday ... starting with 09 ...
We can see a string there.. of sorts ... with in common low digits in the first numbers each day ...last position
Lows being (in this case)digits 1234 5 ..... and highs being 67890
3, 1, 1, 4, 5, 4,,4, 5 ,5 ,4 ,....tah dah 09 high digit 9 last spot
So....we knew one day this string would end ......this string of (x combinations of low digit fella's ...what ever the number of combinations is) ......that all started with numbers ending with low digits would end one day.... and only those combinations that DID not start this way would hit.....and that would be our TARGET POOL to aim our focus.
We knew ahead of time ...this new group (what ever their number) ..... would hit from this LARGE Digit group eventually ...one day. ....and so it or (They) did on Wednesday. We knew who they were ahead of time.... just as soon as we knew and had established what our string actually was.
Keep in mind ....5 digit is not my game and I am pretty sure these groups in this particular ex. are too cumbersome to use effectively .....but its a large enough example to show the idea.
We just knew the eventual winner one day ....would be one of the "OTHER" group ..... however big that group is. They did hit and we knew they would.
We weren't back testing from the Winning number.... in this case ... we already knew before hand (just as soon as we could identify the pattern group String) what our target POOL was gonna be.
or......
After establishing what the current on-going String was (the low digit guys) ......
We could have just as easily targeted on that group that was hitting each day (only) .....playing only from that pool....until it ended on that Wed 7/1/98
Again..... I know these groups may be too large to use effectively in real world play...but served as just examples here.
