Questions and answers
- How is a darts 3-dart average worked out?
- It’s the points you scored divided by the darts you threw, times three. A 501 leg finished in 15 darts is 501 ÷ 15 × 3 = 100.2. The 501 scoreboard asks how many darts the finishing visit took, so the averages stay exact when a leg ends on the first or second dart.
- What’s the difference between Course Handicap and Playing Handicap?
- Your Course Handicap is the number of strokes your Handicap Index is worth on a particular set of tees, using its Slope and Course Rating. Your Playing Handicap is that figure after the allowance for the format, such as 95% for individual Stableford or 85% for four-ball. It’s the Playing Handicap that decides where you get shots on the card.
- Which final-set rule should I choose in the tennis scoreboard?
- For singles following the Grand Slam rule, choose a 10-point tiebreak at 6–6, which all four majors have used since 2022. Most club doubles and many league matches replace the final set with a match tiebreak to 10, and some events play the final set out with no tiebreak. Check the rules of your competition before you start; the setting can’t change mid-match without starting a new one.
- Should I use the Running Pace Calculator or the Race Time Predictor?
- Use the pace calculator when you know two of distance, time and pace and want the third, for example the pace needed for a sub-two-hour half marathon, with splits to follow. Use the predictor to estimate what you could run over a different distance, based on a recent race. It allows for the fact that you slow down over longer distances.
- Are my scores and logs saved?
- Yes. Scoreboards, practice records, parkrun results and golf rounds are saved in your browser on this device as you go, so a refresh or a locked screen doesn’t lose anything. They aren’t sent anywhere and won’t appear on another device. The trackers can download a CSV file if you want a backup.
