I don't recall any formal weight survey by the SCCA or the FVAC, but maybe I missed it. The only survey of sorts that I remember is the poll we started here. Other than that, it seems like this was handled according to the normal procedures for a rule change request. It was submitted, feedback was requested in the form of letters to the CRB, and it was denied. In other words, about the same as 95 percent of other rules change requests!
