What does SmartStart do?

The controller allows four times to be set.  They are labeled Wake, Leave, Return and Sleep.  SmartStart is supposed to learn the lead time to reach a temperature. 

The question is does SmartStart know the difference between Wake/Return vs Leave/Sleep, or are all four set points treated equally?  Does SmartStart only affect the Wake and Return times, or does it apply to all four set points?

I think I've found the answer through observation. It appears that SmartStart works whenever the next cycle is set to a higher temperature, regardless of the name of that cycle. When SmartStart is actually doing something the words SmartStart appear near the bottom of the LCD display.
