Here is what I asked them.
I am curious on the OFFensive Rating for the Chicago Bulls in
1995-1996. At first it was listed at 115.8 which was the highest ever and now it is listed as 115.2. What new calculation has been added? And who has the highest Offensive Rating Ever now?

I changed the way I estimate possessions for the team. Instead of
just using the team's stats, I average the possession estimates for
the team and their opponents. This gives a more stable estimate.
Here's the top ten:
+---------+---------+---------+
| year_id | team_id | off_rtg |
+---------+---------+---------+
| 1987 | LAL | 115.6 |
| 1992 | CHI | 115.5 |
| 1988 | BOS | 115.4 |
| 1996 | CHI | 115.2 |
| 1995 | ORL | 115.1 |
| 1987 | DAL | 114.9 |
| 1995 | SEA | 114.8 |
| 1991 | CHI | 114.6 |
| 1995 | PHO | 114.5 |
| 2005 | PHO | 114.5 |
+---------+---------+---------+
So this seems to be a bit more accurate.
