Basically, what the title says. If someone you know thinks that WMR Tracking is not good enough for Beat Saber, show them this.
The Reverb G2 I used here does have 2 extra cameras over regular WMR, but as other owners are happy to tell you, they don't improve on the Tracking Quality or Tracking Volume in the Up/Down direction. It just expands the band that WMR was already capable of Tracking further to the left and right.
