Jim, the website you are linking to is not a credible or legitimate source of information as there are some serious ethical issues that you, as the owner, refuse to address. Aside from flawed statistical methodology that is discussed extensively on portlandtransport.com, you continually refuse to answer questions relating to potential conflicts of interest nor will you answer any questions that regard financial disclosure. Any reasonable person would question the motivations of an individual who refuses to answer questions such as these.

Unfortunately, I see absolutely no reason why one would trust the conclusions you publish on this website, nor would any research professional in any industry or field. This is not a personal attack, it just an expected practice around the world if one wishes to have their research accepted as legitimate.
