Hi, Recently I strung my racket using a drop weight machine. I strung the mains at 24lbs and the crosses at 26lbs. The job was good. My friend strung another racket using a manual crank machine at 27ilbs crosses and 27lbs main. This is just his method. Both strung one piece design and in the exact same way as he taught me. What was strange was that when tapping the string bed on each racket once strung, my racket sounded MORE high pitch than his. which i guess means that it is a higher tension. So my question is this. If i strung mine at 24x26 and he did his at 27x27 should his be higher tension?! Or is it because i did my crosses 2lbs more that it will make mine higher overall? Im confused as to how this works.... Either that or one of our machines is not calibrated well, and im pritty sure mine is calibrated fine.
