Peak heart rate detection too slow

I've been using the Venu 2 for almost two years and have been satisfied with it. However, my only grievance is the lack of new, useful features in the updates throughout this time.

Today Vivoactive 5 came to me and I have completed my first training session and I am unfortunately disappointed. The sensor is the same as in Venu 2, Elevate 4, so the accuracy of heart rate measurement during training should be the same, but it is not. After finishing the series, Vivoactive 5 needs almost 10 seconds to detect the peak in the heart rate and start recording it, when it already starts to drop.

I have 2 weeks to return it, so I would like to know if there is a chance that this is a software problem and will be fixed in updates.

    All of newer Garmin watches (Forerunner 165, 255, 265, 955, 965, Fenix 7 and Epix pro and non-pro versions) have this same problem. I would not be surprised that it affects all watches of newer generation (that have elevate 4 and 5 generation sensor).

    Garmin introduced different HR algorithm through software updates which made HR tracking very slow to respond and innacurate. Instead of fixing it, they keep buying time pretending that there is no issue sending same generic replies to users to tighten the watch etc. although they actually recognized there was an issue in HR algorithm in last 6 months, but nevertheless did nothing to fix it.

    I think I can confirm that a Vivoactive 5 averages HR over (too) long periods and apparently sometimes gets stuck. It makes them slow reacting, for example:

    I was cycling and while going uphill for 8 minutes, it showed a HR of 70- 80. When I went downhill after that my HR showed between 130 and 150. The next uphill part HR stayed around that number. When I stopped the activity, the HR graph did only show the low HR for the first uphill part, which is definitely NOT correct!

    Why would Garmin make this choice for such a slow/averaging HR algorithm??
