.. New derived data series representing an estimate of core temperature on the basis of HR changes. * shown on AllPlot and RideSummary * 2 new metrics; max and avg core temperature .. This has been based upon "Estimation of human core temperature from sequential heart rate observations" Mark J Buller, William J Tharion, Samuel N Cheuvront, Scott J Montain, Robert W Kenefick, John Castellani, William A Latzka, Warren S Roberts, Mark Richter, Odest Chadwicke Jenkins and Reed W Hoyt.
