It is a last ditch chart. I did use it today. I was looking for an even number. So I could easily ignore any odd recommendations.
Some players use the trailer chart to bypass chart 5 the repeater chart also.
I think the chart would be more helpful if there was another column that displayed the skip of the number so when you were sorting you could see the skip.
I have tried that in excel, but ultimately always abandon it as the time of workout just keeps getting longer and longer as I put more charts into excel.
It is not very hard to memorize the DSH skips to help in the trailer analysis. Three days in a row trying, and you can do it.
I used to do it religiously and interestingly it does build confidence to know the patterns intimately in your head. No other charts or paper needed.
A DSH of 40 numbers is the most I have memorized. Probably hard to memorize the skips for two different games at the same time.
I was trying to decide on if a Last digit 4 or a Last digit 2 was going to come. 12 and 14 were both adjacents.
I picked the 12 as a last digit 2 was missing two draws and a last digit 4 was missing three draws.
It was kind of a counter intuitive choice, but it was correct. But I did not match any other numbers with it.
If you don't believe you are not going to win. The more familiar a player is with a game the better it might work.
