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.
- Angle. Make a 56° angle. The angle to make was 56°, 34° short of a right angle.
- Mark. Mark 2/5 of the way along the line, starting from the dot. 2/5 is 40% of the way along the line from the dot.
- Path. The squiggle is how many bars long? The squiggle bends 2 times. End to end in a straight line it spans 3.4 bars; along the curve it is 6.1.
- Degrees. How many degrees is this angle? The angle drawn was 31°, 59° short of a right angle.
- Center. This arc is part of a circle. Where is its center? The arc was 132° of its circle, 37% of the way round. The shorter the arc, the less it says about its center.
