It's a computer model. They just set it up and let it run, occasionally making updates which they detail on the blog (on the same page as the tracker). They don't manually adjust the numbers at all.
That is my impression from watching the Bloomberg Model 3 Tracker since its inception as well: unusually transparent in its methodology, reliable and non-opinionated. Most of the legitimate criticism the tracker got in the past can be explained with the phase delay their smoothing introduces to VIN registrations - which is a natural property of lagging averages.
Troy's tracker is a tad more accurate for production estimates, and the other data products of his surveys are very valuable, but both trackers are pretty accurate in my experience.
Also, the people running the model are separate from the people writing FUD-for-clicks at Bloomberg. Bloomberg is a big organization with sometimes competing agendas - the Tracker guys are honest and on the good side IMHO.
