Could we have some meaningful detail here? 'halve' over 'days or weeks'? It sounds like the explanatory use of the "Factor of 10" Not helpful.
I beg to disagree with "not helpful". Most people have no idea what is the true
forgetting rate. 50% in days or weeks is roughly true and the best short expression of the rate I can come up with. I added more data to the entry but this verges on theorizing. The best argument against "not helpful" is that, following some not-so-honest mnemonists
?, people tend to belive that we can learn once and remember for ever. In other words, they belive in
forgetting rate of 0. Some reputable scientists also embarked on an effort of proving that true, but the only "zero rate" possible comes from
implicit repetition
Well. In distinction from 0 (zero) I suppose it's helpful. Otherwise you have to admit it's rather broad.
