Hi,
Since a few weeks there are artifact corruptions of more than 20% in my run data. Previously they were in the 1-5% range, but now they are significantly larger. This only affects the running data, the deviations in the cycling data are in the 1-5% range.
I use the Polar H10, I have replaced the strap and the batteries and tried different positions. The result is always bad. I have not changed anything in the watch settings, but maybe there is something that has been reset during an update?
Best regards
Joern
