The scale is generally further subdivided with intervals of one decimal place, although the use of halves (e.g., 7.5) and quarters (e.g., 7+ or 7−, rounded to 0.8 or 0.3) is also common. Thus, a 6.75 could be written as 7− and count as a 6.8, whereas a 7+ would be a 7.25 and count as a 7.3.
In this context, the scale is often further refined with increments of one decimal place, but also accommodates fractional units like halves (e.g., 7+ or 7−) and quarters (e.g., 0.8 or 0.3), allowing for more precise measurements.
