Nice! We're big on being compatible with as many people as reasonably possible, as we've been annoyed by that in other headsets in the past.
* Technically, there's another +-2mm of allowable eye center x/y/z movement that we've reserved for the headset moving around + eye relief. So in theory the maximum IPD would be closer to 81mm, but that puts your right on the edge of reaching our target picture quality.
