In FRC Spyder What Do these mean

[Chowardie]

So my team has been using FRC Spyder for a couple years now and we still don't know what OPR, DPR, and CCWM mean...
Can someone explain what they stand for and what they mean...?

OPR - Offensive Power Rating
DPR - Defensive Power Rating
CCWM - Calculated Contribution to the Winning Margin
They're all statistics that attempt to figure out how effective your robot is at winning the game. This (http://www.chiefdelphi.com/media/papers/2174) post links to Ed Law's whitepaper and his wonderful explanation on the subject.

There are multiple threads covering these acronyms and what they mean. They are worth a read. One major point to be aware of is that these stats are more useful in some games vs others.

The short versions:

OPR stands for "Offensive Power Rating," and is primarily used to determine the contributing power a robot contributes to an alliance. The higher the OPR, the more scoring power a robot will have.

DPR stands for "Defensive Power Rating," and is used to determine how defensive a robot is. It works the same opposite as OPR, the higher lower the better.

CCWM is "Calculated Contribution to Winning Margin," and is used to describe how much of a positive impact a robot brings to an alliance. Higher CCWM indicates more good things will happen to the alliance during a match such as drawing the defense away, providing secondary scoring, and so on.

You can check Ed Law's presentation on OPR and CCWM here. (http://www.chiefdelphi.com/media/papers/2174) I do have a file by Ed Law also on DPR if you want to look at that too. I don't remember how I managed to find this, but I will PM you the file if you would like to see it.

If you're using the Android version, there's a menu item on the Team Stats tab with a question mark icon that displays definitions for these terms.

DPR . ... the higher the better.

Was that a typo?

That was not. That was me misunderstanding the stat. Thanks.
