If you're after improving prediction skills... we need to discuss the methods rather than look at just results. Whether it be an open discussion on methods, tools, formulas, or whatever... accuracy can come a bit later...
but good luck getting people to open up about the systems in use for a jackpot game... for the obvious reasons...
but for the heck of it (and one more attempt to get some open PB discussion going) here's my current system....
1 excel workbook with 4 sheets...
Sheet 1 is a Long Term full history list of sort order numbers drawn set up as such...
say you are on drawing 100, it takes for example the MODE of draws 1 thru 99 and uses that as the guess for draw 100. error correction is performed by taking the difference of the draw result from the MODE prediction, the most frequent error number is counted and used as an error correction factor for that mode. Each time a match is made, it produces a zero, these are counted for a loosely adapted neural network weighting algorithm. I use the following stats, MODE, MEDIAN and FORECAST to get 3 picks, an error corrected pick for each stat. the 3 picks are combined into one using a weighted average formula that takes each stat's position... for example ((MODE WB1*number of correct MODE WB1 hits)+(MEDIAN WB1 * number of correct MEDIAN WB1 hits)+(FORECAST WB1 * number of correct FORECAST WB1 hits)) the whole thing is then divided by the total number of correct WB1 hits... this allows for the one with more correct hits to carry more weight.
Sheet 2 is a Midrange full history list but with stats taken back only 28 draws
for example draw 129 MODE pick compares draw 129 to MODE of draws 100 thru 128. similar calculations to sheet one result in one pick
Sheet 3 is a Short Term full history list that gets it's picks from only the last 3 draws, for example for draw 100, it takes the MODE of draws 97, 98 and 99. similar reduction methods end in one pick.
Sheet 4 is my main sheet, it gathers the picks from sheets 1 thru 3 and uses an overall weighted average to come up with my one pick for the game... all numbers use ROUND rather than INT because round is more accurate where INT just truncates the decimals. Sheet 4 also has a full history list in both draw and sort order and has a freq. counter showing how many times each number was drawn overall AND by position for both draw and sort. I also, for convenience keep mu cash option jackpot calculator on there. It figures jackpot - 35% to accurately give you an idea of what you really would win vs. what they advertise...
And there we have it, for all of its flaws and imperfections, this is how I generate my one pick and of course I am wide open to comments, in particular possible refinements I may have missed (that's how the open discussion would benefit all of us)...
I understand why people would want to avoid opening up with methods, so I suggest the following... open discussion of just picking the red powerball... that would be a coup! let's work on that because then maybe more would be willing to share. ;-)
