[Aavso-photometry] BVRI vs. griz

[Tom Krajci]

Why did the pro's make the switch from BVRI to griz?

Is there an astrophysics advantage?  (Better, more accurate 
classification/ID of stars because the bandpasses don't overlap?)

Is it a better match for typical CCD response?

Other?

Thanks in advance.
