The goals you have set out are, indeed, worthy of the effort and I agree with your general and specific replies. Trying to grasp the complexity of the task you have set for yourselves is not easy at first. Reconciling the manufacturers claims against the critical analysis in the AADF reports requires a significant investment in understanding the process and the meaning of the results when making comparisons. Reducing the results to a meaningful high level summary requires some incredible communications skills.
Giving the problem more thought, I can see how (and why) the information deficit is reflected in the ratings. However, it is probably safe to assume that most people will not want to devote the time to do a detailed evaluation of what is being presented. They will look at the headline number and make a decision. To give greater value to that level of decision-making, may I suggest two ‘flags’ to go with the rating?
First, put a star or a question mark, perhaps, next to the rating number to indicate that it is not based upon complete information. Then add,
Flag 1: “This rating is based upon known information. The manufacturer has not disclosed all of the ingredients used.”
Flag 2: “This rating is based upon known information. The manufacturer has not disclosed the percentage of all the ingredients used.”
One or both flags may apply to a rating.
That sets out the justification for the rating and raises awareness of the issues at the highest level of the presentation. The details regarding the value (or harm) of specific ingredients is already easy to access and the flags might encourage more people to consider that information.
Regardless of my opinionated ramblings, what you are offering is unique and very valuable and I hope you will continue to fight for your principles and continue to share the fruits of your efforts with all of us. Thank you.
