As an example, a linear fit for the relationship between t is and dosage was done (see Table ). The fit result confirms the graphical result that sucrose is the most efficient retarder in the studied set, with a slope of 0.123 compared to 0.104 for etidronic acid and 0.019 for tartaric acid. Furthermore, the fit quality is excellent for etidronic acid with a R 2 value of >0.999 and slightly worse for sucrose (0.986) or tartaric acid (0.955). The visual analysis for sucrose reveals a small deviation from an exponential relationship at larger sucrose dosages, i.e., the slope decreases at larger dosages in a semi-logarithmic plot (see, for example, Figure ). Furthermore, while tartaric acid shows by far the lowest retarding power, its dosage dependence consistently shows an increasing slope in semilogarithmic plots. This implies that the retardation grows faster than exponential.
