I agree. This will involve several visits to submit docs, with each inspector providing their own opinion about what the application should contain. I bet the "arbitrary" application form will become a standardized once the new instructions (регламенты) are issued.
I once used a paid consultant at Sakharovo. It was a waste of time and money because the advice was contradicted by the inspectors. This stands to reason, since the inspectors sometimes contradict one another.
The best advice comes from an inspector, gained by making an application in person. It is also free of charge.
