skwinty,
You are apparently not involved in debate with people about these theories so you are not familiar with how it works. As you say there is no point in trying to convince a believer to change his mind, but there is a very much larger body of people making enquiries. These people are not believers. They are doing what everyone does these days, they are surfing the internet for information. They see both sides. They make up their minds on the basis of the weight of evidence. That graph I am hoping for will add to the weight of evidence.
