RPM released

Always take RPM with a grain of salt.

This. These ESPN secret stats are strictly for entertainment value.

They need to release the formula. We know that xRAPM uses prior informed data. We know that RPM adds boxscore data. But they refuse to publish the formula.
It seems like they changed something this year and it is either the boxscore influence or something about the prior information.
In recent years bigman had a big advantage when it comes to DRPM. It seems like that is gone this year. I would love to hear an explanation for the change.

In the end RAPM is a more reliable number because we know how it is created. Regression of lineups and on/off that can happen with or without prior information.

What are people relying on them for? 

I would be very surprised if any front office/coaching staff in the NBA pays any attention at all to any of these stats. I don't know that for sure, of course. 

I would say that the stats are pretty reliable entertainers however, which is why ESPN keeps putting them out there. A number of fans seem to enjoy parsing them, and a few may even take them seriously. But I don't know if the stats are being relied on for anything of consequence. Fantasy basketball, maybe?

I have no objection to people discussing them or anything, if they find it amusing. Just think that as far as using them to reach some meaningful analytical result, it's pretty much a case of GIGO.
