PS4, Line 50: RUNTIME_FILTER_FPP
I don't feel strongly about this so either way. "FPP" is kind of an opaque 
technical term. Since this might be user facing and we've got a flag already 
called "max_filter_error_rate" which is wordier as a query option but 
incorporating FILTER_ERROR_RATE instead of FPP might make the option more self 
documenting.

Would you mind updating the flag doc to mention the query option as an override?
