You'd be surprised, constantly manually changing the thermostat can have adverse effects, but with PID-based management system, you attempt to heat/cool a little past the target temperature before occupancy. From there you occasionally cool/heat when it hits a deadband of, say, 2 degrees back to the target temperature. After analyzing bills and normalizing area weather, we've been able to show 8-15% savings.
