Polar heart rate

As I don’t have Internet access for the time being it’s a tad difficult to input my polar data so have decided to put it into excel for the time being. Took a short off road ride yesterday out over leafield way and over akeman street, not using runkeeper I relied on the polar heart rate bike computer solely and it came back with some surprising results. Slight variation in the distance compared to runkeeper but the good bit was calories used, as runkeeper basis it’s calculations on standard formula for cycling it does not take into account heart rate and effort so the polar machine was monitoring my heart and adjusting calories burnt, it shows a greater expenditure of calories which makes sense as I’m up hill and down dale all the time, great stuff that I have been burning more than previously thought. Will be using the polar from now on as it gives a more accurate stats of my progress and runkeeper primerily for route logging.
