There is only a 5% advantage going to the 3.55 or 3 MPH at 65 MPH. I assume you mean going from the 3.70:1 set to a 3.55:1 set...

Your assumption is correct
10% gain from 4.11 to 3.70 and 15% gain from 4.11 to 3.55.
Also a car with Power Glide (a torque converter) at a steady higer speed and at a perfect level cruise the engine will be turing about 2% faster due to converter slippage.
