It mentions 99%/97.5% (heating) and 1%/2.5%/5% (cooling).

The main first sentence says "This manual gives uniform engineering 
weather data for winter heating design, heating degree days, summer 
air conditioning design and criteria, for calculating energy 
consumption estimates, and cooling degree days."  (No reference 
document given about those).

Supersedes (several documents from 1967).

Since this was 1978 publication -- I imagine the 1972 HOF might have 
had something?
