I am aware that CH is being recorded, but I am not aware of it being used when there is no adjustment to Gross Score.You may not be seeing any effect on your SDs via NDB/Stableford adjustments, but CH is certainly still being used.
Unless we are to believe that the possibility of it being used amounts to it being used.
