Statistician's Digest: Possessions Numbers Very High and Different

"...Looking at the boxscore of yesterday's playoffs and applying this possession´s formulas:
Poss = (0.96*(FGA + TO - OREB +(0.44*FTA))
I reached to the following numbers
Team A: 105.4
Team B: 114.6

Is this correct ? How can be so different ? Should the "team rebounds" be added to the team total rebounds? Are they all defensive? ...

It seems like those numbers are too high, and can not be so different:

1 - The eBA Basketball Analysis System register the "team rebounds" and apply them to the team total in equal proportions to the offensive and defensive rebounds that are given in the team total. In our reports, where we make a distinction between offensive and defensive team rebounds, team rebounds are included in the team total, but referred separately in a special column.

2 - As I said in the eBA Statistics Clinics, the free throw coefficient is only an estimate. As we stated in this thread, the eBA Basketball Statistics Analysis System looking for exactness, register the real number of times the team reached the line for 2 or 3 free throws with the concept UP TO THE LINE, remarking between parenthesis the number of times the last throw was MADE.

3 - Shots at the end of the period include - in box scores as your´s - "team rebound" that may add possessions that don't really exists - see for reference this thread. Technical FTA are subtracted from the regular FTA, since they aren't really part of any possession.
