Forerunner 255 music HR data messed up????

My high/peakHR for the day says 169bpm on Garmin connect but my MyZone chest strap said peak was 180. During my workout i broadcasted the watch as I was told to do in order for the watch to use my chest strap instead of the watch sensor for better accuracy. So if it used my chest strap then why is it so off? Even if it the watch uses some average it should be in the 170s as I spent over 10 minutes in the 170s. I don’t want to have to manually update this inaccuracy daily. It happens every day but I’m just now asking for help or advice. I don’t want to have to open my myzone app every time to see the “accurate” data. That’s the whole reason I synced my chest strap to my watch…

The watch will always use the strap instead of wrist data in activities as long as the strap is connected, maybe except if you broadcast.....

This means broadcast mode isn’t a way to force the watch to use the strap during a non watch activity like someone on these forums suggested? That person’s reply was met with a few “agreed” responses. I never did understand that. To me broadcast means to share your data with another device so in this case the watch would be sharing its HR with another device. That’s what I imagined and was told that thinking was incorrect. Weird thing is when I did that it was then 100% in sync with my MyZone app. My MyZone app recorded 180 and the watch max HR on garmin connect… 169. Maybe that 169 was from a 2 minute max. Even so, I know for a fact I was in the upper 170s for over 6 minutes.

is there a way to use the chest strap during a non activity? I guess that won’t be common as I just realized there were other activities I could access on my watch. I thought it only had running.. I do a lot of HIIT and conditioning so I’ll throw in a HIIT activity so I can see on the watch what HR my chest strap is recording.

next today I’ll do my HIIT and or touch a thing other than make sure it’s connected to my strap. And see if it’s still off. Last time I did this my strap would show a number pretty different than the watch. Maybe the watch was playing catch-up.

I didn't understand that you wanted it in a non activity, since you wrote about a workout.
