Hello! Hope everyone is feeling good about this and is more ready than I am!

Here is a simple concept I wanted to get some clarification on. The Utility adjusted return formula is:

U = Rp - 0.005(A)(Variance of Portfolio), where A is the risk-aversion factor. From what I have seen, this factor is usually given, for simplicity, in a scale of 1-10 with 10 being the most risk-averse, and then it’s a simple plug from there on.

My confusion is, what if the scale is given as 1-8, with 8 being the most averse? If the investor’s risk averse factor is 6 on a scale of 1-8, what is “A” going to be? simply plug in 6? Or adjust the scale accordingly and enter 7.5 (because 6 is 75% of 8)

Thanks for the last minute help.
