Maybe a year ago I got an email with a link to a marketing video. I've long since deleted it and I forgot who the marketing guru was, but I've seen his name before. The videos was an ad for a copywriting course IIRC.
In the video the speaker told a story about how he was given a sheet of paper with a short bio and list of qualifications by a MA video company and he had to turn it into a sales letter, turning it into an impressive story and tell the customers what the videos would teach them.
He mentioned that in part of the story the instructor was in a bar with a nickle in his pocket and had to fight skinheads, and IIRC that was in TRS' letter selling Chris Clugson's videos.
His point IMO was that you don't really need to know much about the product to write persuasive copy.
That tells me that many of these sales letters are lies, especially if the copywriter gives a long list of bullet-points on what the videos cover and all he saw was a page with a bio and qualifications. I'm pretty sure many of these guys make up the meanings of the info in the bio sheets they get.
I've seen some pretty funny MA mistakes as well, such as an instructor being a 4th Degree Black Belt in Yondan.
