I tried the preset HR for my age and the Ownzone feature.
I also had the perceived rate of exertion chart (PRE)

Now here is the dilemma - when I stay in the HR zone recommended I was only walking about 3 mph, even if I did a brisk walk my HR jumped up too high, slow running was out of the question.
My PRE was about at get up from the couch to get a beer level
I bumped the parameters up to HIGH and then could do a sloooooow run. but now the HR was at 145-150. I decided to keep running the track and see how long I could go. I was doing a 12 min mile and ran for an hour, barely broke a sweat and could carry on an easy conversation. But my HR was steady at 145-50 which is the supposedly 80% rate for me where I should only be speaking in short sentances, passed lactate threshold, and breathing heavily
I'm not 100% sure but I'm pretty sure that polar just use a fairly simple algorithm to work out HRM (like 220 - age) and then apply that to an ideal workout rate of 65 - 85% MHR which to be honest may not be ideal for you.
