How far outside a yeast's published range a primary can be before we flag
it, in °C.
A range published in whole °C and a schedule entered in whole °F can't line
up exactly. 59 °F is 15.0 °C but 64 °F is 17.8 °C, and a brewer who entered
the edge of the range they were shown should count as inside it. Half a
degree Celsius is just under one Fahrenheit degree, which covers the
rounding in a °F entry.
