The medians are compared as differences in percentage and L/h.
aThe results reported by Booysen et al. (2019b) were based on a mean reduction, and used only a week before and a week after maintenance. This paper used 3 weeks prior, 3 weeks subsequent to maintenance, and 3 weeks a year later. The results are therefore not directly comparable and only given as a reference.
