When would you close up the class boundaries?

For example 3, why is it not from 29.5 to 31.5 and then the midpoint is 30.5. I know it gives the same midpoint by the way but it changes the class boundaries should you need to find the median value from linear interpolation.

When do we add 1 to find the median and when do we not?
