One thing I've noticed of late is how, on certain routes, the Saturday frequency is actually less than Monday to Friday daytime, off-peak. Examples include the Bluestar routes 2, 11, 12, 16 and 19.
In my experience buses are actually busier on Saturday daytimes, compared to Mon-Fri daytimes, due to weekend shopping; Sat is certainly the busiest day in the city centre.
So why are Sat frequencies often less than Mon-Fri off-peak?
Going back to previous eras, the converse appeared to be true: for example I was looking at some GMPTE bus timetables from the 70s recently and the Sat frequency was similar to Mon-Fri peak, and greater than Mon-Fri off-peak.
