Based on what I know about Racquettune's algorithm, if the same string factor is used for all the measurements on a racquet, the tension loss reported should be pretty good. The absolute readings may not be spot on though.
As a double-check for tension loss, try this ... Let's say one day RT tells you the frequency is f1. A week later, tension drops and RT says the frequency is a lower number, f2. The percentage of tension retained should be the square of f2/f1. In other words, the tension is now (f2/f1) * (f2/f1) * 100 percent of what it was when you measured f1.
When you do it this way, the string density is not a factor because it divides itself out in the equations RT uses. I'd be interested to see how well my theory holds water.
