Can confirm that the daily/weekly service changes are deeply confusing. A lot of information is implied through the MTA's frequently terse announcements of service changes. For instance, I was waiting for a R train in the Canal St. station last weekend wanting to go to the Dekalb Ave. station. But then a N train started to come into the station on a platform it's not supposed to be on. A glance at the paper announcing this change said that the N would run on the R track between Canal St. and Dekalb Ave. Does that mean the N would stop at Dekalb Ave (a stop it ordinarily would not make)? I didn't know and the MTA app's arrival ETAs for the Dekalb Ave station indicated that it would not. The "Next Stops" board inside the N train indicated that yes, the N train would stop at Dekalb Ave. If I boarded the N and it turned out it wouldn't stop at Dekalb Ave., it would take me ~15 minutes to backtrack. So I decided to wait for the next R instead.
