On a copy of a real library (8,067 cards, 20,907 reviews, 20 studysets), every open list read every card (0.8 s), every review (0.25 s) and replayed schedules after every change, each on its own: the library, every studyset open on the stack and its topics. - CardRepository keeps each studyset's cards and every card's stamp until a card changes; a read begun before a change keeps nothing. - ReviewRepository keeps the whole log once many cards' reviews are asked for, updated by this device's writes and read anew after a sync brings others'. - StudysetProgressRepository works out every studyset's progress once for every list and hands the last to whoever follows it next; StudysetListBloc reads it. A full recount now takes about 65 ms. Home no longer rereads every revision after each rating.
