This method you are speaking of cps10, is what I use as part of my formula...and YES it does work in pick 4 as well.
But, what you need, is a "formula" that will give you 4 "pairs" that will definately come up in the next few drawings, and then you just play all the ten "x" numbers to follow it.
Example, 09* pair would be 091, 090, 092, 093, 094, 095, 096, 097, 098, 099....10 numbers to play...same goes for pick 4....
091* would be 0911, 0912, 0910, 0913, 0914, 0915, 0916, 0917, 0918, 0919.....
So, with 4 "pairs" and ten numbers per pair, that's only 40 numbers to play. :)
Using my formula, the MAX missed I've seen, from looking through 4-5 years of pick 3 and pick 4 drawings was 17 misses, including midday and evening....so, about 8 days, but, if you manage your money right (either offline or online...offline is better, bigger payouts, easier to play all the sets, etc.), you can come out with atleast $2500+ profit from pick 3, and double that from pick 4. :) Right now I'm working really hard on making my formula better, so the "misses" are dropped down to about 4-5 drawings.
You'd be suprised at how much the "signal" you can get, "given off" from the drawings in other states, can aid in precise prediction of the numbers in "partner" states.
Just watch a few of my posts, and play along with me. I guarantee you'll make some $$! :)
