In the context of 'Memory and Forgetting', according to the study of the famous 'Forgetting Curve' conducted in 1885 by German psychologist Hermann Ebbinghaus, what is the rate of forgetting in the initial period immediately following learning, and what is the primary educational implication of the 'Savings Score' discovered by Ebbinghaus?

Hermann Ebbinghaus propounded the 'Forgetting Curve' through his famous experiments in 1885 in 'Memory: A Contribution to Experimental Psychology'. According to him, most of the newly learned information (such as nonsense syllables) is forgotten very quickly—over 50% within the first 20 to 60 minutes immediately following learning, meaning the rate of forgetting is extremely high initially. Thereafter, the rate of forgetting slows down. Ebbinghaus used the 'Savings Method', where he compared the time or effort required to relearn material with the time it took to learn it the first time. The 'Savings Score' measures how much 'savings' in time/effort occurred in relearning compared to original learning, proving that a portion still remains safely preserved in the brain unconsciously.
