weather or heat pump?

is the weather just way more mild this november than last year, or is my new heat pump really starting to pay off?? it's probably some of both.

november 2008 - 845 kWh
november 2009 - 421 kWh

that's roughly half of the usage! the next three months will be especially telling because they are traditionally the highest electricity usage for me.
