* There are multiple formulas for calculating water vapor pressure which produce slightly different results.
* The calculation of skin temperature is not straightforward. The calculator uses Neilson's simplistic approach for 0 Celsius to 15 Celsius, then rather than the Mehnert for above 15 Celsiusformula.
* The maximum running pace is calculated using a goal seek algorithm.
* The various formulas for calculating the surface area of the skin appear to give similar results.
