@capetocuba , Mark is right. You had me confused there. 30% flavouring, approximately. Based on the story i put in the Notes there, that 3 extra flavour shots would make it 30%, but since read another comment - also in the Notes. Now i've reduced the Coumarin Pipe to 23.3%, reducing the total to 26.7%, which slightly increases the proportion of Vanilla Icecream and Marshmallow. ...i think i'll reduce the Coumarin Pipe to around 20%. And all this would have to change when i start using the RDA.
