APBRmetrics

In calculating the pace adjustment for PER, does Hollinger define a team possession as

(a) Tm FGA + 0.4 * Tm FTA - 1.07 * (Tm ORB / (Tm ORB + Opp DRB)) * (Tm FGA - Tm FG) + Tm TOV -- from basketball-reference

or

(b) Tm FGA - Tm ORB + Tm TO + (Tm Fta)*.44 -- from hoopdata

?

Also, does anyone know how he accounts for players that have played on multiple team? For the team stats, I am currently using a minutes played weighted average.

It should be (I'm 99% sure it is)

Team Poss = 0.5 * ((Field Goal Attempts + 0.4 * Free Throw Attempts - 1.07 * (Offensive Rebounds / (Offensive Rebounds + Opponent Defensive Rebounds)) * (Field Goal Attempts - FG) + Turnovers) + (Opponent Field Goal Attempts + 0.4 * Opponent Free Throw Attempts - 1.07 * (Opponent Offensive Rebounds / (Opponent Offensive Rebounds + Defensive Rebounds)) * (Opponent Field Goal Attempts - Opponent FG) + Opponent Turnovers)).

Team Pace = Team Poss / Team Min * 240

This how I calculate team pace too for any metric.

As for players that have played on multiple teams, I guess he uses something along the lines of

(Player Minutes on Team1 * Team1 Pace + Player Minutes on Team2 * Team Pace) / Player Total Minutes

If he doesn't, then he does something wrong.

Great, thanks!

Team Poss = 0.5 * ((Field Goal Attempts + 0.4 * Free Throw Attempts - 1.07 * (Offensive Rebounds / (Offensive Rebounds + Opponent Defensive Rebounds)) * (Field Goal Attempts - FG) + Turnovers) + (Opponent Field Goal Attempts + 0.4 * Opponent Free Throw Attempts - 1.07 * (Opponent Offensive Rebounds / (Opponent Offensive Rebounds + Defensive Rebounds)) * (Opponent Field Goal Attempts - Opponent FG) + Opponent Turnovers)).

Should this be the adequate formula to calculate/estimate possessions in a basketball game for a team, can someone explain in with some stat numbers and in a step-by-step process? Just to avoid confusion by others who might ask the same thing. Thanks.
