Well we can go a bunch of different ways here ... and I think this is where we would have to decide if this strategy is for the long haul run and just to have coverage, then picking the high ranking ones won't differ much whether the entire history is used or the last 100 games, because the same #'s will be in there. The problem would come when trying to narrow down the "right" power #'s if this were going to be a wheel in constant play. I'm not sure which I prefer, hence why no recent jackpot yet!!! If trying to create the wheel for spot play (meaning using those special "3-5" along with the currents for the next 3 draws) then any number of groups can work which brings us back to trying to create that killer pool; which from my experience means overlapping wheels pulling the numbers from a variety of charts (and just trying things). If you notice, on any given day one chart (let's say chart 4) can contain all 5 winners; and on other days you'll see 2 here, 2 somewhere else and maybe just 1 from another.
My latest creation of 2 wheels is using this strategy, but has me in a holding pattern because I chose one power number for each wheel (example: my "10 & Friends") where 10 is the power number and its a matter of waiting for that group to show strong in the L10, then I'll pounce ...
The idea being that these numbers will roll around and come together every so often because history has shown that it does, and so if patient (keep in mind this is a sort of base wheel and not the only one to play at any given time) a 4 out of 5 is pretty much guaranteed. As well as 3 of 5's. The ultimate 5 of 5 could come as well. I just don't want to be playing a wheel for what seems like forever so that even if a "4" does materialize it just barely pays back what was spent!
