Australian League BPM

Apologies if this seems very naive, but what would need to be undertaken to move BPM across to a different league? If I am able to obtain all of the relevant box score statistics, would I be able to use the NBA coefficients in another league such as the Australian or New Zealand league? Or would I have to run another regression?
I've tried giving it a crack but got some pretty strange results.

Yes, it should be possible. I've done it in the NCAA with good results. It won't be as accurate as on the NBA, but basketball is basketball (unless the Australian league has some odd context).
The process is:
1. Calculate advanced stats
2. Calculate adjusted team ratings
3. Calculate raw BPM
4. Apply team adjustment
If you'd like, I can take a look at the spreadsheet/code.

I think I may have it somewhat down.
A player that is averaging 36.661 MPG, has an ORB% of 4.8965, a DRB% of 17.5524, STL% of 2.1903, BLK% of 0.7866, AST% of 15.7123, TOV% of .1353 (when converted into the correct format), a 30.9514 USG%, TS% of .4656 on a team with a TS% of .5253, a 3PAr of .2807 in a league that has a 3PAr of .3067 producing a raw BPM of 5.0610 sound about right?
Also, with 40 minute games would I need to alter the MPG coefficient by dividing by 5/6ths?

I just checked your numbers, they look right.
I'm not sure what to do with the MPG coefficient. I think adjusting as you proposed would probably be best.
Let me know how it all works out!
