Now that the patent was granted and since Rossi has emphasized for so long that the past patent rejections were the only reason why he has not said more.
The following is the ultimate way to judge credibility:
Nobody has the right to ask Rossi to tell about the optimization of the E-Cat which is his trade secret.
BUT
Rossi should now help replicators to get an UNoptimized System working IF he wants to be taken serious. An unoptimized system that is producing a small but(!) undeniable amount of excess heat.
If he refuses to do this we can finally judge that the E-Cat is a scam. There is no reason to deny this to the replicators from now on.
