Darts 501/301 Scoreboard

About this tool
Enter each visit’s total and the scoreboard does the rest: it takes it off, moves to the next player, and shows the recommended checkout once someone is on 170 or less. A visit that would leave 1, go below zero, or finish on anything but a double is a bust, so the score goes back to what it was. When someone checks out you choose how many darts the finishing visit took, which keeps the averages exact.
The 3-dart average is points scored divided by darts thrown, times three; the first-9 average uses only each leg’s first nine darts, which shows scoring power before the finish. Legs alternate who throws first. The match is saved on this device, so a refresh or a dropped phone loses nothing, and Undo goes back a visit at a time.
