The Last Digit of the Sum, it is the King of the filters.
So far, I like that filter better than any of the other filters.
LDS, SLD, LDR, whatever, it does not matter how you call any of the filters, all that matters is what they show on the past draws and on how they are used.

The Last Digit of the Sum can be a good filter (That is an under statement), it has 10 equal patterns, from 0 to 9 and each digit pattern equals 1/10 of the total 1000 straight numbers, that is 100 pick 3 numbers, as with some other filters it can be used for both, straight and boxed filtration.

There, on those draws, the last digit of the sum, repeated only 2 times from the last draw to the very next draw, that is 2 times out of 27 times, not bad, but there is much more than that, you can figure that out if you study the patterns.

Who-ever invented that filter pattern, Win D or whoever, deserves great praise and I am not kidding about that.

On some of my past posts maybe I have one or more possible ways of using it.

Every-time that you filter out one of the digits of that filter, you filter out 1/10 of the total pick 3 numbers, mighty it is, but there are other filters that are also mighty, then Why is this one the King for?, because unlike some other filters, it can also be stable-dependable, each of the patterns is equal to the others and it should also be easier to use and understand.

On some older posts I give the basics and maybe also the intermediate ways of how to use it.

You can also by yourself figure some ways of using it, maybe looking at things such as skips of the patterns (Which in this filter are digits) and also at the digits differences, that is at the numeric differences of the digits themselves, that is at the numeric differences of any-one digit in relation to any other digit, maybe you can figure out some other way or ways of using it.

Think: "Statistical Relationships"

"The proper use of "Statistical Relationships" is the art of prediction". Says Lottery Post's LANTERN-Fernando (Myself).

At the very least, the art of lottery prediction, but probably applies to any or many kinds of prediction.

I know that I am not giving much info here, but the words statistical relationships should give you a hint, besides I do give a little more info on some older posts.

Relationships of the filter's digits to each other as "Symbols-patterns" and also as "Numbers-patterns", that is another good hint.

Read the old filters posts (But not everything is on the posts, but enough to start with it is) and also develop your own ways.

Roots next sometime.
