Looking for a generic Power Burner boiler efficiency curve

I am trying to find a curve that shows boiler efficiency versus load. This curve can then be used to plot expected seasonal efficiency. I've done that with the attached PDF combining it with weather data to get a quite accurate method to predict fuel savings for proper boiler sizing. It would be really nice to get one for full on/ full off cycling, for hi/lo and for full mod based on outdoor reset. I had some for oil boilers, but can't find them are the moment. I figured the modern oil boiler curve would be very similiar to gas power burner
