The “Exponential Subjective Scoring” is just a way for nodes to rate the validity of chain forks. The longest chain (in terms of time) wins. Whereas in Bitcoin the longest chain (in terms of computational effort) wins.
I have to say Vitamin B is long on makeing up new terms, but short on programing/algo cred. Sorta the opposite of satoshi.
