I wear the sensor over my bibs
Over my bibs. I started getting more consistent readings when I started putting it over them
Over bibs for the breathing sensor and under bibs at the front for the HR monitor as recommended
But how do you guys do wearing a baselayer and bibs … ?

As @Dave_Reed wrote above, plus a base layer and a jersey on top.
I don’t think I’ve seen Dave’s response regarding how he wears his base layer and jersey. I understand how the sensor should be positioned on the outside of the bib shorts 
I just find it a bit inconvenient to wear the base layer over the bib shorts, since the natural way would be to wear the base layer underneath.
You’re absolutely right that the base layer goes under the bibs. But personally, for me, I don’t see any difference whether my thin mesh base layer top is worn over the bibs.
Honestly, I figure - wear the same thing during tests that you wear for training

In the context of breathing rate (BR), the Tyme team shared a PubMed link link.
Researchers found that a two-hour cycling session reduces the power at which the transition from moderate to high intensity occurs. While total ventilation at the threshold remains unchanged, the breathing pattern shifts: athletes start breathing more frequently but with lower tidal volume.
These findings suggest that fatigue forces the body to change its physiological strategy to maintain performance.
I noticed this when analyzing easy sessions where heart rate and ventilation did not change, but I clearly felt fatigue. That raised the question: how to define “enough.” BR could be a signal here. It seems likely the team will refine this metric for monitoring easy training.

i think this was for @kevinrambaud to possibly explain the indoor/outdoor reading differences 
i’ve always worn the sensor under bibs and a base layer.
i did reposition the strap so that one of the sensor pucks is under the bib strap and the other is more to the side, which seemed to improve readings outside.
Honestly, I figure - wear the same thing during tests that you wear for training
this is the key

I’ve tried both. Under and over my bibs outdoor. Indoor I didn’t put the straps at all. I should try one indoor session over my bibs with the app and with my Garmin Edge 1040 to have an exact comparison.

I wear my base layer and any other layers over my bib shorts, though one set is actually a short rather than bib short.

I just did an endurance indoor session today using my Garmin Edge 1040 with a bibs without the straps on like I did with the Tymewear iOS app and VE is now at the same level. That was it.
Since I did the Threshold test with no straps on, my VE values are based on this way of wearing my bibs with does not translate the same way when having the straps on and the sensor above it. I’ll do my next test in a few weeks with the straps on and sensor above to mimic how I’m dressed outdoor.

Yes please, would be very welcome.
I like the app very much.
But on the Garmin Edge it would be fantastic.
We will look into it. I assume the preference would be for everything to be measured by power?
hello,
That would be absolutely brilliant if power could be added.
But the main thing is VE.
It is intended for cycling, and finding thresholds during testing.
But the tests are always performed with power.
There is now an automatic detection of your zones within a ride, but I can not see how to use those zones instead of the last test ones. I know, just go and do a test, but my trainer isn’t playing ball so I would need to do it outside, which is fine but finding a constant grade hill that lasts 30 minutes is difficult
I have send the following questions to Tymewear:
How does the automatic detection actually work, and which parameters define the different zones?
For example, I can see from today’s training ride that my “detected” zones are significantly lower than the ones I established during my test in February.
Also, how do you expect users to actually use the autodetection? I assume it doesn’t work live during a workout via something like a Garmin Connect data field on a Garmin Edge device.
So would the idea be that you get updated zones after a workout, and then use those for your next session—where new zones might again be detected? Or how is it intended to work?
How often should the baseline metrics be update, for example the HRV and resting heartrate can go up and down on daily basis?
And they answer the following:
This is a beta feature that uses breathing metrics and HR to estimate training zones. The resting values don’t need to be updated frequently as they don’t really change, the HRV isn’t used for anything at the moment but could become an interesting daily recovery metric down the line.
The idea is to replace threshold tests for users that don’t want to do them. We’ll keep iterating on this and building out the feature in the coming weeks.

Credit to the Tymewear team they continuously roll out improvements and updates in a soft-launch mode
Regarding the automatic threshold detection feature, it is still in beta, so I usually don’t rely on it. But there are some very interesting options, such as comparing segments within a workout or comparing two workouts — I find this extremely useful.
I can clearly see when my “easy” second session is actually not easy at all. Or how breathing rate reflects central nervous system fatigue during long sessions, even when ventilation, heart rate, power, and even lactate remain stable.
Overall, there is a huge amount of useful information.
And if they enable real-time automatic threshold detection… there will be nothing more to add.
if the issue is between your phone/tymewear app and your trainer: you don’t have to use the tymewear app to run the test.
- create a custom workout that mimics the ramp test in whatever software works with your trainer
- execute the test
- get that activity into tymewear
- mark it as a threshold test (the last time i did this, i had to set it in both the phone app and webapp)
i’ve used this method a couple of times so that i can shorten the interval lengths around expected FTP as 3-minute blocks after threshold gives me lower-than-expected values after VT2.

has anyone tried the new intervals.icu integration? the warning about possible duplicate activities is giving me pause.
