As a stringer, my question is: who cares? I absolutely understand where you're coming from, and to the average player, they ARE playing with "60 lbs" (or whatever). It's a stiffness, and it's exactly the same (in their minds). Equipment junky or not, the idea is the same. While we may know that they in fact have a string bed roughly equivalent to 40 some lbs, even WE don't know for sure.
Even if we have reasonable measuring devices, they only give us dynamic "tension," and/or stiffness measurements. Even the string meter is only a reference device (used to track tension loss, etc).
At the end of the day, i assert that nobody knows exactly what tension their racquet is, nor should they lose any sleep over it. If someone requests 60 lbs, and they feel like the strings are "too powerful," i will educate them about what can cause this, and what it means to string at "60 lbs," but I find that most players don't really even care to understand that much! I will often give a brief "pep talk" to a new customer about who strung their racquets before, and that it's common to have a string job feel a little different (for different reasons, including technique, machine type, etc). I find that tennis is an extremely mental game, and taking a little bit of the doubt out of switching to someone new does wonders for repeat customers. If it doesn't feel right, I ask customers to let me know HOW it doesn't feel right, make adjustments accordingly, and without their knowing it, I just helped them understand better what a reference tension really is.
