APBRmetrics

Apologies if this seems very naive, but I have a couple of questions related to calculation BPM. I already read article (http://www.basketball-reference.com/about/bpm.html) and calculated of Korean League BPM but got some strange results.

1. BPM_Team_Adjustment = [Team_Rating*120% - S(Player_%Min*Player_RawBPM)]/5
For this equation, what are the meaning of 'S' and 'Team_Rating'? I used 'net rating without adjustment' as 'Team_Rating', is this right? On the other hand, I completely don't know 'S' parameter. If 'S' is related to SOS or SRS, is there any alter parameter for that? I'm not sure that I'm able to get some metric related to schedule.

2. Multiply 'BPM_Team_Adjustment' and 'Raw BPM' together and I get final BPM, If I get 'BPM_Team_Adjustment' and 'Raw BPM'. Is this right?

The 5 is is representing the 5 men on the court for a team at any given time. Team Rating is the team's efficiency differential (ORtg-DRtg) if no Adj. Net Rtg is available, S, I believe is the sum of the team's players Raw BPM's. DSmok1 is the creator of BPM. He could answer any questions you may have about BPM. It's been awhile since I've calculated it, but I think the team adjustment is added or subtracted to each players Raw BPM, instead of multiplied. That could be a reason you're results are funky.
