I made an Ontario version of BlueGal1's Left-Right Chart. Ours has to be different because we have a field of only 70 numbers in ON, whereas NY has 80 numbers. Because of that, the last digits do not line up from Left-side to Right-side, and neither do the tens groups (decades). But Smart Luck Advantage Plus software can be used for those 2 needs.
So the ON L-R chart has 35 numbers on each side, in 7 groups of 5. They are lettered A thru N. These are all the 20 winning numbers from each draw, spread out evenly from left to right, and then circling back around. Having the chart laid out this way, even if you do it with pen and paper, will allow you to continue to add more winning numbers to the bottom, from upcoming draws.
The purpose of this chart is now only two-fold. 1) If one of the groups is entirely missing from a draw, you will see that in most cases this group returns in the next draw. (I have highlighted the games where a group is entirely missing). For the most part, the missing group will show up in the next draw - only a few times will a group be missing twice in a row. So that gives you a heads-up to expect at least one of the 5 numbers from the group will probably hit. 2) Also, if fewer numbers hit from the left side of the chart in this draw, in many cases it looks like more numbers will hit on the left side next time, to make up for it. And vice-versa with the right side of the chart. So again, you may want to plan your plays around this.
Interestingly, the only 2 groups that did not have a miss in these last 10 draws shown in the picture was the first group (A) and the last group (N).
Another interesting thing is that the number(s) that hit after a miss most often (but not all of the time) seem to be a different number than the one that did hit just before the miss. For example, in Group D, 4 and 32 were the numbers that hit just before the miss, and then it was the numbers 18 and 46 that came back after the miss.
Some groups are pretty empty (like group H), and some numbers are heavy-hitters (like #5).
@BlueGal1, if there is anything else we should be making note of in the L-R chart, please chime in :)
