Prof. Gruber "No one has ever questioned the quality" of GMSIM

That's a quote from today's hearing (about the 46 minute mark), referring to the Gruber MicroSImulation Model.  It's reminiscent of this quote:

Both claims are contradicted here, especially Chapter 7.

The testimony also said that he was happy to "answer questions about the model and how it works" but I received no reply to the inquiry I sent Professor Gruber by email June 10, almost 3 months before my book would be published containing criticisms of GMSIM.
