      I will start a new topic because too much writing in a single topic. This is a skyrunning event so it includes running, hiking, and some scrambling. The comparison between the S9PP OHR and a smartsensor on the chest is very good (according to me). And this was with beta, pre-release software.

        @isazi looks pretty good. Could it be that watch has more problems in lower HRs around 120bpm for ascending because of cadence somehow? Think the sections with high bpms worked better for me… 80-100 steps per minute could be typical for hiking and HR around 110-120 bpm (Zone1 and 2, not race) does not differ that much from that. Your bpm above is significant higher than maybe hiking cadence.

        I also remember that S9PP OHR was on downhill running higher than smart sensor, which also could indicate a somehow cadence lock.

        My cadence flat running is around 180 and also differs much from my typical running HR. This could be why flat running is very good for me.

        Does OHR work different in mountaineering profile than trailrunning? Guess not, but have to check.

          @mountainChris I don’t know, I have pretty good results with the S9PP, I hope it can also improve for you in the future with some upgrades.

            As always, OHR is very personal, and it seems to work fine with my physiology, so YMMV.
            In this case it is three watches, two on the wrist (including Sapporo, the S9PP) and one on the handlebars paired with a chest strap. It is gravel riding, with some pretty rough sections.
            The graph is not 100% perfect, but definitely very good for me.

              @isazi gravel riding is for me also very good! There is no “cadence swinging or steps”… Did it same way. S9B / smart sensor on handlebar. S9P on wrist…

              What I will try is, to make a custom sport mode trail running for hikes, not mountaineering. Just to be sure…

                @isazi Do you have training hikes with lower HR and comparison to smart sensor?

                  @mountainChris not that I can easily find, I basically never hike with the chest strap, only with OHR. Maybe I will find some time during winter holidays for this, but that’s in two months from now.

                    @isazi ok, and single lower ohr hikes over altitude profile without compare?

                        Thanks @isazi .
                        Yesterday’s cycling for me.
                        Used S9PP basic MTB profile, and SmartSensor paired with Locus on smartphone

                        I had good result while running once, but this session of riding is totally wrong.

                          @Mff73 yes. I know this very well for hiking. It seems that some users or some activities or some combinations of that do not work at all. For now it is totally unknown for us why.

                          Would be interesting if this will be heavily analysed by Suunto and if there is a chance of improvement. Or if it is just what it is. I missed Improvements for S9P and therefore went with S9 and Smartsensor, which I wanted to only wear in winter.

                            Things are now little clearer. I went out today for an easy walk (no sports), did a custom trailrunning profile, were I could see my HR. Then I went with cadence round about 120 steps per minute steady and flat. Watch can show this and also cadence can easily checked twice with phone stop watch. Watch showed also round about 120 bpm in HR. But I checked HR with other watch and sensor. Can also easily done with stopwatch and finger check. Real HR was only round about 90 bpm.

                            –> so watch has high capability to get in a cadence lock during walking

                            Probably a problem of every OHR device. Crucial could be the mixture of weak HR on arm and not so robust sensor (weak sensor and probably no effective filter algorithms) with interference from other things (cadence, mtb riding)…

                            For me it does not work again and I am little bit disappointed to bring watch that easy in a cadence lock. Only with a walk on a warm day…

                              @mountainChris maybe this will be improved with fw updates.

                                @DMytro Hope so. Are there things around the corner in beta SW?

                                    @mountainChris Unfortunately this will vary on an individual basis. I have very little cadence lock with the Pro even when using poles. I can provide examples if you like.

                                      @Brad_Olwin yes of course individual. But you are saying, that it is what it is and there won’t be any updates to enhance robustness, better interference filters, … so that is more useable for a certain group of customers?

                                      Do you have walking (no sport) comparison?

                                        Today just a walk again with both watches. S9 with smart sensor. Again great difference just walking in not cold weather. OHR not usable. OHR was not direct cadence lock all the time. It was in between cadence and real HR. At the end I stood 2 min and couldn’t believe what a saw. Also with no walking motion big gap. No change within 2 min! See picture after 2min standing. It seems that there is a big overlay or watch is lagging behind and waiting to get another trigger and until then it is just guessing… more and more believe higher intensity maybe better than lower. Also changed watch positions with almost no effect.

                                        Additionally I found this.
                                        https://www.correrunamaraton.com/en/suunto-9-peak-pro-opinion-initial/
                                        „The pulse sensor is also new. Or new by half, because the sensor changes slightly with respect to the previous one (it is now proprietary to Suunto), but the algorithm continues to be that of LifeQ. At least for the time being, because the forecast is that there Suunto will also take over.“

                                        Can this be confirmed? Please Suunto take over 🙏😀

                                        @isazi @Brad_Olwin Sure your pre-release not production versions didn’t have already a draft of new Suuntos own algo?

                                          @mountainChris Not necessarily no improvement but my walking and your walking experiences are very different. Yes, I have walking but not sure a belt to compare to, I would have S9Baro or S9Peak compared to S9PPro

                                            I’ve been getting real bad OHR readings with S9PP over my first two runs thus far. See attached images of two easy runs for me, where real effort has been at HR Z1 mostly.

                                            Circle in yellow is the time it’s been reading close to my effort, you can see OHR real high with wrong reading most of the run, for the second image that big drop is because I took the watch off and put it back on. Also second image is with today’s software update applied.

                                            I have slim wrist but I’m using the watch with the same fit I used S9P which only during cold day runs would’ve given me such bad readings, which is not this case.

                                            I’ll keep trying to find my sweet spot for S9PP OHR I guess 🙂
