Random Walk--skip movement signs

[LouisBachelier]

The skip reports "winning reports" provide 2 basic information: the length of the skip and a sign (plus or minus) showing the increase or decrease from the previous draw.

The table below is a statistics of the signs as reported by the "winning report" for a parpaluck of 10000 trials (or drawings) applied on a file of 5 millions of records for a 49/5 lottery game.
The PLUS sign has been replaces by +1 and the Minus sign by -1 (in absence of sign for a zero value of the skip, +1 has been considered)

see attachment 1

One observes that for 2/3 of the trials, the sum of 3 consecutive movements is ZERO.

Based on the statistics, one can also calculate the probability for any sequence of positive and negative movements; as an example, below are some of these probabilities for various sequences of + and -, as applied to a selection of Salusian filters.
