I use the previous weeks woth of numbers Midday and Evening Combined.That's 12 - 13 or 14 sets of numbers depending on the states. On States like Florida with one draw a day I use only 7 sets and still get results.

I like to use the history to see what has followed the number in the past.

Does that work often? if so , what states?

I don't think it's necessary to go longer back than 50 draws. 10 is also OK.

Once in a while the lotteries change the set of balls and the statistics should start from scratch again.

I use exactly 28 days. It's a natural cycle of moon and fertility so it can't be all wrong. Midday and evening draw states give you the optimum of a little over 50 draws during that cycle....Perfect.

Hmm I use 10 days now (in general). I dunno where Perkis' idea is based, but I would bet Gail Howard knows better.

Exactly... I can tell everytime they change the balls from my "Bell-Curve."

The draw history should be related to the size of the game, especially for lottos.
For the 5/53 part of Powerball it is interesting to bear in mind that after 50 draws
there is likely to remain on average only 0.47 numbers not yet drawn. Thus if there
are one or more not drawn it would be tempting to bet on them in the hope of getting
at least some money back.

Seems everyone has a 'system' regarding drawing history. I think it all depends on how many sets one is going to play. For example, to play all numbers in 5/52 one must play 11 sets in order to get every number into play. If one plays a lesser number of sets, then some numbers will have to be left out. In this case, one must refer to other means. I usually play 5 sets, 25 of the 52 numbers. I try to maintain a balance. For example, I choose 4 single numbers, 5 teens, 5 20s, 5 30s, 5 40s and 1 50s.

l then refer to my skips charts for each number series. For example (my data is accurate +/- 3) there is a wide difference in when the numbers last came up. For example, 4 hasn't shown up in 33 drawings. 5 hasn't been seen for 26 drawings. In fact, all single numbers, except 2,3,8 haven't come for 10 or more drawings.

In the teens series, good old 13 has been around for 33 drawings. 16 and 18 haven't shown up for 16 and 13 drawings, respectively. 15 and 19 haven't been seen for 8 drawings each.

My data for the 20s shows 20 and 26 haven't come up for 20 and 27 drawings, respectively.

Further, 33 and 36 havn't been seen for 26 and 24 drawings.

The data for the 40s suggests number 46 has been lost. It hasn't come up for 47 drawings! 48 hasn't been seen for 36 draws and 49 hasn't come around for 28 drawings.
Number 50 hasn't been seen for 29 drawings.
The problem of course is trying to figure out which of the 25 numbers to play. All hot, meaning they have come up in last 5 drawings or all cold. Maybe some warm ones! Or a mixture. I've tried several different ways. The fact that I'm here should tell you I haven't been successful!
The main question is how much history is best. My answer is as far back as is necessary to ensure that all numbers are being considered, which for MM means 47 drawings in order to get number 46 into play.

I think Codemaster has the right approach. Use multiple draw history ranges....

for 5/39:

39/5=7.8, so get total occurrences thru 8 games back..the average occurrence will be 1

2x7.8=15.6, then ocurrences thru 16 games back will be approximately 2

so on, and so forth.

Each occurrence(s) for selected game ranges can ten be sorted (ascendingly) and tracked in excel to find distribution limits.

L	L	L	L	L	COL		L	L	L	L	L	TOT
1	2	3	4	5	CNT		1	2	3	4	5

0	0	1	3	3	3	4	14	22.6
0	0	1	2	3	4	5	1	1.61
0	2	2	2	4	3		62
0	0	1	1	1	2
0	1	1	3	3	3		1	2	3	4	5
0	1	1	1	2	3	"0-1"	98.4
0	1	2	4	5	5	"0-2"		100
0	1	2	2	4	4	"1-2"			98.4
0	1	1	1	3	3	"1-3"				98.4
2	2	2	3	4	3	"1-4"					96.8
1	1	1	1	2	2

By using multiple game ranges, it sets up a somewhat reliable method for eliminating unlikely numbers for the next draw.

Hypersoniq:
Thank you for posting the Powerball history with the ball set and machine number. Very interesting! I can't wait to analyze!
Do the MegaMillion people publish their ball set/machine changes??
