Round by round
A round scores 100 for a guess within a small margin of the truth and falls in a straight line to 0 for a wild one; the day is the average of the five. The pictures are the game — these are the figures behind them.
- Path. The squiggle is how many bars long? The squiggle bends 4 times. End to end in a straight line it spans 1.7 bars; along the curve it is 3.5.
- Ratio. By area, the big circle is how many of the small one? The big circle is 3.39 times as wide as the small one, and area goes as the square of the width: 3.39 × 3.39 is 11.5.
- Mark. Mark 2/7 of the way along the line, starting from the dot. 2/7 is 29% of the way along the line from the dot.
- Aim. Where will the arrow hit the wall? The arrow’s line had to be carried on 4.7 times the arrow’s own length to reach the wall.
- Meet. If these two lines carried on, where would they meet? The lines meet at 115°, after carrying on 0.6 and 1.3 times their drawn lengths.
