The way I have been using it is to start with 0, and look for the last drawn combination that had a 0 in it (I'm working mid to mid, but you could try combined, or eve to eve.) When I find a drawn number with a 0 in it, I look at the next day's draw to see what follows that 0. I keep working backwards, looking for draws with a 0 (any position,) and see what the next day's drawing brings. Usually at least a couple of digits will pop out as the ones to plug into the template next to 0, and I can make a guess between two or three others to fill the third position. If you're looking for a straight hit, it's important to plug each digit into the correct position ( if I knew the specifics on how to do that, I would tell you. I just use intuitive guesswork.)
Once that's done, keep working down the list doing the same for 1, 2, 3, etc.
So, how far back should you be looking? When I first started playing around with this, I was going back over two months' worth of draws, and this was too far, I think. One month seemed better. But as ScreamingMidget pointed out, Florida has been playing really wonky lately, and now I'm trying to find the digits within a two-week span of draws. Just play around and try to get a feel for what's best for your state.
A couple of tips:
The “Save As” function is your friend. Early on I had plugged in some digits, and in backtesting they seemed to be hitting pretty good, even some straight hits. And then I started “tweaking” the numbers before I realized I hadn't saved the previous ones. Now every time I start playing around with the file, I do a “Save As” adding the date to the file name so I don't confuse myself!
When you enter the number from the last draw and hit enter to generate new combinations, look just to the right, and you will see what looks like a reference box, or tic tac toe box. I have seen numbers from this box hit, like all three digits from the first vertical column will hit, and this is a combination that won't show in the generated combinations
