Speed versus RPM calculator

I found a web page, Speed versus RPM calculator that allows you to input different variables to figure out what RPMs you will running with different rear-ends, tires, etc. I have a stock 2012 V6 with a 2.70 rear end. At 80 MPH my tack says 2K RPMs. If I put in a 3:55 rear end this web page shows I will be running 2,650 RPMs at 80 MPH. Does this sound about right?

3.55 / 2.7 x 2k = 2629 RPM @ 80 MPH

So, the speed calculator sounds about right to me.
