I purposely avoided explaining it to demonstrate a point: the average user doesn't know this or understand it. They understand the outcome only.

Sorry, you are 100% correct with the SSID vs MAC. If I'm in my car with the handset externally powered, does it use course location or does it use all three sources because on KitKat on my Moto G, it gives me the option to use all three at cost of battery life?

I disagree with your assessment of the location ability. It's definitely better than you explain it. I can go through at least 100 previous data points in my history and it's spot on each time.
