Turn off Heart Rate Clipping

1

Is it possible to turn off heart rate clipping?

It clips on HRmax, so yours is set to low.
Display the HRraw plot and check what your highest value was. But be aware of false spikes.

Actually it’s set too high so it doesn’t clip which is annoying when it comes to heart rate settings because my max heart rate can change throughout the session. I suppose I can just put in HR zones manually and not use percentages which is also annoying. I don’t see why this clipping feature is needed with modern HR monitors, it should be optional.

I don’t understand a word about what you’re saying…
Your HR max is a physiological number. You set it to whatever you have reached over the last 6 months or even 2 years during a super hard effort. Once you have that number, it will only change slightly down with age.
If you use HR reserve for load calculation or zone setup, you need this number to be correct and not fiddle with it to do something else.
You can set your HR zones completely as you want but you have to enter them as % of LTHR, so you need to do some math. Your zones in Intervals are not referenced to HRmax.

There is no reason to clip heart rate.

Pardon my lack of perfect precision in explaining what I mean. It is completely reasonable for someone to start training, do what they think is hard effort to get max HR but not actually get it. They could subsequently keep up their training and then do a good hard anerobic work and see a new max HR they were not able to hit before. It is also perfectly possible after six months of training to not be able to hit a max HR you hit early in the season after rest. Why force clipping on every user? Why not make it an option for those with HR monitors that are problematic?

The way Intervals is build, requires it to be able to attribute all data points to a zone.
If data points are out of range, that´s impossible.
And I still don´t see what the problem is, because if the data is all valid, clipping means that your value is set too low, and you should correct it.
Can you share your use-case?

Just attribute anything over maxHR to the highest zone.:man_shrugging:t2:

The zones are calculated from threshold HR. So I think the question is legitimate, what is the benefit of the max-hr value or for what is it used? I could not answer this, only knowing that everything above will be ‘clipped’.

If you don’t have any use of this, you can easily set it to 250 or so. After that click “Update Zones” above. You should never see any clipped values again.

As in my post a bit higher up, when using HRreserve or TRIMP, it does impact the calculations.

You can also choose to display the Raw Heart Rate chart which will be unclipped.

Why not just have these calculations ceiling at maxHR without clipping the HR data and effecting other ride measures.

But if you wen’t over maxHR it wouldn’t report it in the general stats.

You’re not telling us where you want to go, so it’s impossible for us to give any meaningful answers.
I’m just a moderator here on the forum, no dev. There are a lot of requests for additions, modified behaviour, etc, on the todo list and depending on demand/workload, they get some sort of a priority. No one ever had any special remarks regarding the way HRmax is treated, and AFAIK, it is very similar on most platforms: HRmax is HRmax, and if you get a true value above what is set, you change the setting. If we had an idea of what you’re trying to achieve, we might jump on the wagon…

Things are Clipped for various reasons. The simplest reason is to ensure correct / most sane data for analysis.

while intervals.icu can use the arbitary limit of 220bpm as the max, but it’s a bit much/ridiculous.

This sentence/statement is also a bit weird. Yes, your maxHR can/may change over the course of your lifetime, but as others has pointed out, the Max is the Max. in fact, you can also just put in 220bpm as the “lifetime” max and be done with it.

The only difference I can think of is your % of MaxHR number will invariably change as your maxHr change thru your season.

some coaches / sites will also ask you to keep 1 number as the max. Same like Stryd will tell you not to update your weight and keep it at 100kg (last I heard, havent been following)

I’ve never had an analytics platform clip HR data on the HR trace graph. And years ago I was also surprised by power data “cleanup” of perfectly good power data. I’m not a fan of automatically modifying and displaying data that was not recorded.

18

As with the 80/20 rule, 80% of the users are of “is a fan” variety. Sticking to the defaults and knowing that some amount of care and thought was placed into designing the defaults so they do not need to know more.

19

I’d wager more than 80% of users don’t have a clue.

As a paying user I wish it could be disabled, like the power spike feature. In general creating data is not a good idea. But I understand why the decision was made.

But it’s not a big deal.
