So the pass rates for the last 7 grands have been 16.5%, 19.2%, 15.7%, 13.5%, 13.4%, 20.9%, and 31.1%. Looks like there has been a big rise in the pass rate. Is this due to a standards/rule change? It doesn't seem very random. I think this is good for the HRC. If pass rates would have hung in the 13-15% range people would have gotten very discouraged.
