Hi, As stated in the title, everything was good but now the ratio and score are fluctuating like crazy. I've tried unplugging/plugging back in the device, as well as wiping the sensor clean, but none of these actions solved my problem. I've attached a readout of the data from a quick session I had today, in case that's helpful in diagnosing what the issue might be. Thanks. Jeff

I get the infrared sensor that's measuring oxygen levels/blood in my PFC, but what I'm confused about is how is this increased over time, especially by me just sitting and staring at the screen? I'm curious how this works and do think the science is accurate, but I'm also partly confused and thinking I'm doing it wrong/I should be trying to focus in a particular way. Can someone help me understand exactly how using this device improve blood levels in the PFC, and also apparently mood, focus, etc.? Thanks

Next try: I used a different laptop than the computer I used the web app on again only as a power source (because the laptop is too old for the web app). The computer I use the web app on needs a power supply, but my wall plug destroys the signal. My room was pretty dark, because of my blackout curtains. I did 4 tries and always reset the data in between. They were all the same basically: ratio : was very stable from 0,59 - 0,62. Sometimes it was the same for about 10 seconds or so. From what Joshua wrote so far, it should be pretty stable and from 0.5-2. score : around 0.10 score line : was very flat I think these values don't necessarily mean I've done something wrong, but: The circle only changed a very very small bit, if at all. Almost not visible. I'm pretty sure that I wasn't able to influence it. The very small movements seemed random. The band was pretty tight/tense. I think the LEDs were pressed into my forehead too much. See the picture. 😂 I also felt my pulse, so I think the band was too narrow. Can this be a problem? I wore it like this to prevent light going from the LEDs to the sensor directly. But for the last attempt I made the headband about 5cm wider and still got the same results. During one attempt I pressed the LEDs more into my head and the ratio and the graph went down. But during a later attempt nothing happened at first, but after it the ratio remained a bit higher. Or could it be possible that there's nothing wrong and that it just takes a few sessions to be able to change the circle? But unfortunately I don't that's the case, because people can use e.g. the mendi device successfully from the first session on.
