Daox,

You are right about the therm reduction (60.8 to 51.0 =-16.12). However the reduction of degree days is 1029 to 911 = -11.47.

So , despite a decrease in the heating load of ~ 11.5%, there was a reduction in gas usage of 16%.

Maybe that difference was where the 5% reduction came from . . . .
