Availability vs. Capacity

[keithboone]

Current reporting includes "All X" and "X in use", but does not include a value of "X available for use", likely because
All X - X in use is presumed to mean X available for use.

This allows computation of a capacity measure as the ratio of X in use / All X (e.g., a hospital with 20 ICU beds where 17 are in use is at 85% capacity), but does not allow search by "hospitals with more than 2 beds available" without having to do computation in the search.

If the measure were restructured to include All X, X in use, and X available for use, then the search could be performed.

Add note about the above wrt to Guideance, show CDC as implemented, and then with application of guidance.
