Proposal​

Guus Razoux Schultz started developing CFCE in September, 1981 [1]. A few months later, Schultz learned of the F2L pair concept and integrated it into his method.

Schultz described the method's origins to me in the above private message.

World Rubik's Cube Championship 1982​

Schultz used CFCE at the World Rubik's Cube Championship 1982 [2]. This makes Schultz the first person to have used the F2L pairing technique in an official World Cube Association competition.
