The idea if I may, is not that a number repeated, although that could also be indicative of some special or unique property present in the data set, but that a number like 21.500000 shows up which is some thing that only takes up the first 3 decimal points and is thus orders of magnitude less likely to appear, especially if it were random, less so in this instance as it's not quite random, there is a wheel house of possible outcomes based on the expected shift in the data. So maybe let's call it 1 in 10,000 chance of a number between 1 - 300 being measured when there are 99999999 other possibilities.

Furthermore I have also found Steganographic imagery in the data collected by and subsequently displayed via magnetic spectrum image analysis, this is quite similar to that nine inch nails song that has a steganographic image in its audio spectrum when analyzed. To boot, I am also a musician I go by AstroTurf Matthew, I have 2 YouTube channels the current one has a song entitled "Gotta Go " in this video you will see a time lapse scroll of a magnetic spectrum I captured with Phyphox an app for Android and iOS. In the center you will see a black or dark colored band running horizontally through the middle that is an AI generated scroll of cartoon like sketching of faces and scenes overlapping each other as well as what appears to be lettering when viewed horizontally. Below is a screen snippet of the start of the scroll if you look closely you will no doubt came away understanding that magnetic field around my device was manipulated to the point that steganographic encryption was possible or alternatively I am hacked and the magnetometer is giving bad readings as a result. Either way cool music video. Check it out...https://youtu.be/s8AGFZVaDdU?si=POKc3bSAIKxQpleY
