The power save mode was meant more to shut it down at night, hence the wierd times and Awaken before Sleep.
24 hours is Midnight of the next day, so 25 is 1am next day, 26 is 2am next day, 27 is 3 am next day.
It's kind of convoluted, but here's the best way (i think) of setting up what you're going for:
Usage Window 1: Specific Day, check M, Tu, W, Th, Fri. awaken 17:30, sleep 27:30.
Usage Window 2: Specific Day, check Sat, Sun. awaken 3:45, sleep 27:30.
This should result in the drive being off between 3:30am and 5:30pm M-F, then off at 3:30am for 15 minutes on saturday and sunday. You can try setting Usage Window 2 to awaken at 3:30 to avoid the 15 minute down time on saturday and sunday, but I'm not sure if it will work.
