Within Switzerland fares are totally under SBB control; mixing countries "special" fares from SNCF (France) may also play a role.
Some of the SBB pricing "assumes" a half-fare card is being used.
They have "super saver" fares on some routes, but when you buy one of them you must travel at a particular time and date (they sell insurance should you need to revise your itn.)
Added note: For Oct. 4 ("random date"), they had a SS fare as low as 45(SFr) (without using a half-fare card). November is not yet on sale, most likely the SS fare table would be similar in Nov. [The official fare is 99SFr\
