How was it determined that the ratio should be 75-25? You are telling me that there is no document to support that weighting. Why was a 75-25 split chosen? What criteria were used to determine that the ratio should be 75-25? I find that very hard to understand, if you do not have any documents to support this decision. It seems arbitrary to me.
