FranksOutChart.gif V4.3 Most dart "Out" charts are tailored (Taylor-ed? LOL) to give the perfect most efficient solutions to finish a game. This new chart is finish solutions for players who haven't attained a high level of excellence in their play. Also read my Discussion on Out Charts V4.3 for the reasoning behind differences from other Out Charts.
Also I've come up with a concept that makes your approach to 170 very simple to remember. You can read the whole thing to understand it, but all you have to remember is like one short paragraph that covers a pattern that works for numbers from 170 to 310. Check out "Approaching 170 Simplified".
The WDF's Out Chart is what you will find on the World Dart Federation's website, under "Basics of Darts". I guess if anyone knows the ultimate solutions for good players, it's them!
The WDF's Rules is a PDF format document of the rules of play from a darts authority.
This is a compilation of many Leagues standards of Ethics and ettiquette concerning what to do / not to do while scorekeeping and shooting.
