Hello John,
Thank you for sharing your criticism of the model. I don't think you are missing anything based on FEV analytics' public disclosures. Their methods are proprietary and black box. We cover firms promulgating new solutions because harried investment folk rarely hear about some of these new technologies and new firms offering them. See, for example, my articles covering XBRL and firms making use of that data. As with any new offering, nothing beats your own due diligence.
Yours, in service,
Jason
