I where under the impression that so-so where between known and unknown. Still, in the list I can see that words that i just marked at so-so is scheduled the next time in 13 month. Why? It is a relatively new word that I have had right a few times and it do contain 3 characters, two of them that i have marked as blue when individual and the last as only known usually but this time as so-so. Is the SRS for words based on the combined weight of all the three characters? I guess that I will have the individual character back sooner or is that a wrong assumption?
