When you look at the heart rate graph after your run why are there random gaps between some of the readings? Checking the watch whilst running there is always a reading.
 
Sometimes it just has difficulty picking up a true reading.

But I'm lucky to even have a graph 40-50% of the time....super annoying.
 
It could be that you wear the watch not snug enough and it has difficulty reading. Or your movements just too quick.
Chest strap HRM would solve this problem if it’s so important to you.

which Apple Watch do you have? my first gen just kept spinning a lot of the time in the gym. 3rd gen was much better almost always showed what it was without waiting. 4th gen is the same no issues with it keeping my heart rate at the gym
 
It depends on the sport. It works well on cycling/spinning but it works very bad while running or swimming.

I think it is related to the movement or maybe because you are sweating more. I don’t know, I practice triathlon and only have good measures while cycling.

Not to mention that when I wear my chest strap the number of rpms decreases always around 20. The difference is so big between the watch and the strap.

I had a S0 in the past and have a S3 nowadays. Both the same. I don’t believe any HRM measures from the watch, just use them as an “indicator” or when I forgot my chest strap.

BR!

2nd....nice to hear it might be functioning more consistently in the later versions!
