You can ascertain how fat a vtubers ass is by the gutterality of their farts. This is a logical science.
For example, mio's brap was a short rasp, which makes sense given that most Japanese women are not blessed like marine is. She was also on the floor, which likely pressed her cheeks together and caused additional noise, meaning her standard brap is likely even lighter.
Meanwhile Mori, whomst marine acknowledges as a potentially dangerous opponent in Ass-Sumo, ripped wet slappy blasts into the shitter. Ollie's spluttery ripper suggested the presence of uncharacteristically large Indonesian cheeks.
By performing detailed waveform analysis and measuring methane ejection trajectories we may be able to surmise the exact dimensions of a vtuber's butt from their braps alone.
