1.2 to 1.4 from the wall is LOW. You are lucky to have such good AC. I don't own a device that shows the THD, but do read a lot of threads about folks power conditioners etc. 4% is pretty common. And I would call the mean... most likely over 3%
THD on AC mains--what level is typical?
My power conditioner has a display that according to the manual shows the % of total harmonic distortion in the AC that's going into the unit. So far I've seen values from 1.20 to 1.40. Is there any range that can be thought of as typical of THD on AC supplies?
