The system doesn't cover doubles or triples, the idea is to chart the days and play when all different is due which is a little more then half of the time. As draws tend to come in clusters rather than alternate you are supposed to be able to chart and predict which type of drawing is due so you know which to play.
In the same sense, nothing prdvents the player from working up two or three of these sets of eight for better coverage.
System sellers make big claims for these sets and charge $99. for a personalized set. They don't do as well as their buyer's would hope for. There is a missing connection between what's happening in the game and what is essentiality a 2if3in10 wheel. A wheel is only as good as how it is loaded if you have hopes for it winning above its guarantee.
Someday someone will figure out how to line this wheel up with their Pick-3 game data and take their state to the cleaners. BobP
