Hi Adjoy, 

This is not really an ANSYS simulation product support type question, and is somewhat out of scope of this Student Community's primary purpose. However it's still are really good question, and as you've discovered there is very little public domain data on this topic. There's nothing that I can point you to other than to state that 70% - 80% is likely a very good estimate, as simulation has become a very popular tool in engineering to save both time and money.
