Perhaps both, but not necessarily indefinitely as the results vary from one day to another.
Each day presents a new subset of variables for validation.

Will do.

Not feasible. Subsets are derived from a variety of statistical predefined formulas. These change for every event date and will need to be validated based on such narrow statistical margins to reduce the possible results which may be presented as "valid options".

A strict mathematical formula cannot be applied.

As such sampling only serves to implement uncertainty in "valid options" which "could be" valid instead of checking each option set which actually falls within the statistical margins.
