anyone experience erractic readings such as 230 HR or maybe even 110km for speed while using the HRM ? Seems that its interference caused by traffic perhaps.. but the strange thing is when i dload the file which has these errors to the PPP3 software the software reduces my Max HR to 136 instead of the 213 which is shown on my watch receiver . So is this a error correction feature or some thing in the software? Cos for the rest of the files which didnt have such erratic readings the dload info is the same or at most + or - 1 difference.
