    Just got the Jan issue of RSI. It's not there.

    Is that the same as the online version?

    It's mid April already and Google still can't find it. Is RSI just abandoning the chart or is it still expected to be published? Or am I just not finding it?

    Why is it needed? RSI uses the same test protocol as TW University, but TW University tests more strings and measures many more things than RSI. RSI measures total tension loss and stiffness. TWU measures four different kinds of tension loss, stiffness, energy return, dwell time, deflection, peak impact tension, peak impact force, etc., etc. In addition, RSI tests at only one tension at one simulated swing speed. TWU tests three tensions, each at three different swingspeeds.

    Agreed, TW has the most data. It just takes a little more querying to get the list you want.

    Yeah, the RSI table is simple and easy to approach. The TW tools are much deeper but you need to spend some time with them. Once familiar, though, and there is so much at your fingertips.

    Anybody can give a more detailed explanation of how the stiffness figure is derived. I just don't understand how the test is carried out by stretching the string for one inch.

    The stiffness ranking of some of the strings are different between TW and RSI.

    For example black widow is rank as softer compared with yonex tour pro in RSI but is stiffer in TW ranking.

    I can't answer your question but I will caution you to use the stiffness numbers as a guideline. Your arm will be the ultimate judge of stiffness.
