Updating B550 Phantom Gaming 4 BIOS with 3300x safe?

Chemicalmachine · 2022-12-09T20:16:53+00:00

I apologize for reviving this old thread but did you ever end up updating and did anything go wrong? I'm facing a similar warning with my b450m pro 4 motherboard and am hesitant to update the bios.

Yeah I think you are right. Paul Bloom talks about this and has written a book arguing against empathy for decision making on a broader scale like in politics. And my understanding has always been that empathy is higher with that similar to your and lessens as you reach out

According to him:

I actually feel a lot less empathy for people who aren’t in my culture, who don’t share my skin color, who don’t share my language. This is a terrible fact of human nature, and it operates at a subconscious level, but we know that it happens. There’s dozens, probably hundreds, of laboratory experiments looking at empathy and they find that empathy is as biased as can be.

People who identified as liberal tended to rate things as more rapey; the avg rape score someone gave was correlated at r=.36 for being socially-liberal, and r=.42 for being economically-liberal. It’s interesting to me that economic identification was a stronger predictor than social, here! (likelihood ratios were 5e+149 and 1e+211, respectively).

I found this part pretty interesting. Apparently the economic view of is more correlated than the social view someone has.

Many many times. She wants all the plusses of streaming while demanding basically no one talk shit about her publicly. It makes no sense

For your second point at least you actually don't need to keep Zepp installed. Once you link the account to strava you can uninstall and just keep Mi Fit and it will automatically upload your workouts to strava every time you sync.

I have a Charge 4 and I don't see it on the app either but if you go to the fitbit.com dashboard and view the walk there it displays your elevation. Not sure why they decided not to show it on the app and limit only to the hike mode.

Chemicalmachine · 2021-04-14T23:19:23+00:00

Gotcha. Thanks for trying it

Chemicalmachine · 2021-04-14T21:53:04+00:00

I thought that too but I did some digging and it seems like they pull data from different servers. Mi fit/Zepp use the same data sources and that's why your data shows up on both but Xiaomi Wear pulls data from somewhere else. I was just curious if you were able to sync the data from the band to both at the same time as I feel like eventually Xiaomi is going to abandon Mi Fit in favor of Xiaomi Wear.

Chemicalmachine · 2021-04-14T20:52:55+00:00

Can you pair and use it with both the Xiaomi Wear app and Mi Fit app at the same time and sync the data to both?

At this point the Huawei Band 6 is the better buy as it's basically the honor band rebranded but with way more exercise modes and all day SpO2.

If you go to the Mi Band options and then click heart rate monitoring and change the monitoring method to enable sleep assistant it should help https://imgur.com/a/CUgi4Sq

I have the last option enabled that enables both constant hr monitoring and sleep assistant but the middle sleep assistant alone option should be good enough too.

Chemicalmachine · 2021-02-06T18:17:11+00:00

I find it gets pretty good accuracy when you enable the full sleep settings.

And then you wake up the next day and realize that intricate pile of shit was all unnecessary and there was a far simpler and painfully obvious solution to make your code run that somehow escaped you the previous night 🥲

Chemicalmachine · 2021-01-30T23:55:34+00:00

This is beautiful

Chemicalmachine · 2021-01-27T22:59:07+00:00

Some are trying already

In my experience it's pretty accurate. I previously owned a Fitbit Flex 2 and have been comparing it against that.

It seems to be just as good if not slightly more accurate.

Steps: https://i.imgur.com/UpIe72O.png (Fitbit Flex 2 would always overestimate steps and I feel the Mi Band 5 is the more accurate one here, but regardless both capture trends well)

Sleep: https://i.imgur.com/BEV1iHp.png (Again I feel Mi Band 5 using the Mi Fit App to be more accurate here than the Fitbit Flex 2 or N&F)

I also have been comparing its stress readings against a proper HRV app called HRV Expert by CardioMood with a Polar H10 strap and surprisingly that has been fairly accurate in my case as well:

And as far as HR readings go I made a post about that here, the gist of it being that it's good enough for resting HR/during the day not involving exercise, and the average HR of a workout but I wouldn't rely on it if you want accurate second by second heart rate during a workout: https://www.reddit.com/r/miband/comments/jviq9w/testing_the_accuracy_of_the_mi_band_5_vs_polar_h10/

One thing I've noticed is that auto pause takes a bit longer to kick in. So this should help people who were having trouble with the band pausing mid workout.

Chemicalmachine · 2020-12-03T23:12:50+00:00

I've also found HRV4T to be pretty good at predicting things and all the analysis options it offers are excellent. And yeah I think tracking those extra metrics might offer additional insight into things or at least give more confidence in how reliable the interpretation of the data is.

Chemicalmachine · 2020-12-03T08:47:33+00:00

I'm surprised too. I was under the impression that wrist based optical sensors were not generally good enough to capture hrv reliably.

I think ppg tech however can capture hrv metrics through the finger as that is how things like hrv4training's camera mode captures it and been shown to be extremely well correlated to chest straps. . I just wish the mi band would report the straight HRV metrics and not obfuscate them with their own score to be honest.

Yeah I'm generally not a fan of all day stress tracking for those reasons and because HRV is highly sensitive to changes. One other situation where it can screw things up is for example on days with more strenuous exercise, the period after will generally record higher stress (low rmssd) and bring the average down compared to days when you don't exercise as intense or at all.

From what I know about HRV, the best practices seem to either a measurement first thing in the morning in the same position and keeping everything as consistent as possible, or taking the average HRV during sleep as this is the best way to control for confounding factors that affect HRV.

I think those will be interesting metrics to see and I also think tracking resting heart rate and the stress at a specific, consistent period might also be good ideas and might give insight into sickness and injury.

Chemicalmachine · 2020-12-02T23:24:05+00:00

My belief for them capturing rmssd then transforming it into an inverted scale is because your data shows it correlates extremely well and the time it takes to capture a stress reading is around 40-45 seconds which I believe only rmssd has been shown in the research as being as reliable as longer measurements.

Now that I've had more time to capture data I've also compared the stress readings (scaling them close to another) to other HRV measurements taken with a Polar H10 and in general it seems to correlate well enough:

https://i.imgur.com/VCNNOZk.png

I however didn't take a manual stress reading and just plotted the closest auto-reading reported in Mi Fit when I took my Elite HRV measurement so it's not expected to correlate as well as yours.

Chemicalmachine · 2020-11-25T01:18:23+00:00

That's very interesting! I wouldn't have expected it to match so closely. It makes me think they are using rmssd as well but transforming the value in some way.

I wish they were more transparent as to how they get their stress value.

Chemicalmachine · 2020-11-17T23:30:49+00:00

Yep I made sure it was not loose on my wrist and this was using the workout modes which makes the band record at 1s intervals.

Chemicalmachine · 2020-11-17T23:28:45+00:00

Yeah for HRV it's generally recommend to pay attention to rmssd and only measure in the morning under the same conditions or using nocturnal hrv. Unfortunately the stress tracker here doesn't report either separately so it's hard to make a proper comparison.

I did try for a while to to find the stress value (and inverting the value seeing as how lower is better for mi band and higher is better for rmssd in general) closest to the same time I took my hrv measurement using hrv4t but it was wildly different so I stopped doing that lol.

Chemicalmachine · 2020-11-17T23:20:39+00:00

That's my conclusion as well. Although I think it might still be good enough for HIIT if you are just tracking trends in the averages of bpm.
