By 0.9 offices / headcount I mean the ratio of space allocated to your team (number of physical offices) versus the number of people. The closer that is to one, the more people get their own, private office. At least when I was at Microsoft, private offices were about a 2nd year perk in good teams, and 3rd-5th year one in less profitable / high profile orgs.
I was sort of joking because that was "above my pay grade" - building and floor-level negotiations happen at the SVP->General Manager levels and down at the bottom we were mainly fighting for scraps or percentage of our allocation that was along windows vs. interiors.
