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 4.5 bars; along the curve it is 7.2.
- Degrees. How many degrees is this angle? The angle drawn was 145°, 55° past a right angle.
- Average. Where is the average height of these bars? 8 bars, at 58, 28, 25, 54, 100, 28, 90 and 95% of the tallest. Their average is 60%, above the halfway line.
- Center. This arc is part of a circle. Where is its center? The arc was 111° of its circle, 31% of the way round. The shorter the arc, the less it says about its center.
- Mark. Mark 1/8 of the way along the line, starting from the dot. 1/8 is 13% of the way along the line from the dot.
