So the reason why we're measuring the core temperature all the time is to get a better understanding of the intensity versus the output like it's very easy to measure the power on the bike but then to see how it compares to my heart rate and now we can even do it with the core temperature to see how much the core is increasing at a high intensity in the same way we can see how the heart rate is ramping up and up and maybe even getting dropped leth-oh so it's just another sensor that's giving us a better understanding of the intensity
