Just a quick two comments.

1-- When people here say (as Jimbo did) that the Jakes are not credible, they mean something specific. They are talking about differences in methodology that make no sense, figures that make no sense (even to a relatively informed lay person, let alone a figure maker), and the refusal of anyone over there to be transparent and even discuss the relevant issues. This is not my religion or soccer team is better because it's mine. There have been a million discussions here about the nuts and bolts of this subject, and there is informative stuff in the Archives section of this site (like "Changing Track Speeds", which even after all these years has not been addressed by anyone over there).

2-- I run a business. The market for my product and Jake's is the same. It's my JOB to try and point out their inadequacies and errors, and to try to get their customers. And believe me, it has worked. To paraphrase a guy named Sy Syms who used to have TV ads here in NY, "An informed handicapper is our best customer."
