Secondly, from a physics point of view, circles and spheres can become stronger under pressure. So that was my reason for asking if the minimum tension recommendation gave the racket a inward pressure which strengthened it.
My guess is that there is still similar stress placed on all around the racquet at ball impact, so the stresses are similar.
Add that to the fact that people have been stringing in the 30s for a while and it doesn't seem to cause problems.
I think the racquet mfgers often put 50-60 as a range as this is the historical range for optimal performance. We're likely to see the low number decrease as polys and low tensions become more mainstream.
