Yes. Your answers suggest a string family, and polyester or hybrid recommendations use a lower starting tension. All suggestions stay within your entered range. Your stringer should confirm the exact product and installation.
This calculator is for strung tennis rackets. Pickleball paddles do not have strings or a string tension setting.
A softer setup may change how your racket feels, but this tool cannot diagnose or treat arm pain. If playing hurts, pause and seek appropriate advice rather than relying on a string change.
