Question about activity calories.

This weekend I am repainting a hallway in my house.  I took off doors and painted them.  On CC is says something like I burn 215 calories an hour.  I have been doing it all day but it doesn't seem that strenuous, but I am still working hard.  Do you think it is fairly accurate calories burned?  I am 5'5", female, 23yrs old and 120lbs.
