Again, it’s heat source dependent. You may be correct for electric or hydronic heat which takes much longer to raise the temp of the room.

Temp rise, insulation, duty cycles are also important factors. Your blanket statement of maintaining 68 all day is better is incorrect.

Department of Energy disagrees: "During winter, the lower the interior temperature, the slower the heat loss. So the longer your house remains at the lower temperature, the more energy you save, because your house has lost less energy than it would have at the higher temperature."
