"standard error" of OPR values

[Ether]

Getting back to the original question:

Do you think the concept of standard error applies to the individual computed values of OPR, given the way OPR is computed and the data from which it is computed?

Why or why not?

If yes: explain how you would propose to compute the standard error for each OPR value, what assumptions would need to be made about the model and the data in order for said computed standard error values to be meaningful, and how the standard error values should be interpreted.

So for those of you who answered "yes":

Pick an authoritative (within the field of statistics) definition for standard error, and compute that "standard error" for each Team's OPR for the attached example.
