59 checkout
In short
59 checks out in two darts under double out: S19, D20, for 19 + 40. If the double 20 lands in the single 20, 20 is left and still on: D10. And if the double 10 drops into the single 10 as well, 10 is left for the next visit: D5. With a single dart in hand, T9 leaves 32, so D16. Under straight out, where any segment can finish: T17, S8.

When a dart strays
A missed treble or double often drops into the single of the same segment, and a missed bull into the 25 around it. Here is what that leaves, and what comes next.
