It does not reflect energy efficiency, so it is not a predictor of the largest component of compressed air life cycle costs: electricity usage. Compressor cost and specific power (kW/100 cfm) Specific power is the true measure of a compressor''s efficiency, so combining this with unit cost is a better indicator of compressor value.
