In RT, what string factor do you use for Velocity? I found the string, but comes with a NaN value for this.The app is cheap ... and cheap entertainment. I don't trust the actual measurement that much, but it seems to me more than likely the measure of tension loss is accurate. That's all I am interested in anyway. Also ... I don't need RT to tell me Velocity plays pretty much the same until it breaks for me. I remember years ago when I played with Sensation loving it for first couple of weeks, and then a definite change (deader). They could have changed/improved it by now. I never feel that way with Velocity ... maybe because it doesn't have an "initial lively" period. But also ... it never feels dead to me, even past 20 hours. Part of it might be the fact I rotate the racquet (which edge up) around 10-15 hours depending on notching. My wear pattern is center to top edge. I get less notching in the center because of tight middle 8 strings... and more on the hits closer to the edge/tip. I get a little "new string fresh feel" on rotation.
My guess is I would usually break Velocity 16g at 15-20 hours if I didn't rotate. This little strange quirk gives me an additional 10-15 hours. Sure ... I could spin my racquet and look cool ... but I have some of that cheap SOB in me to. Actually ... mainly I don't want to drive to the stringer ... make that lazy cheap SOB.
It does occur to me if I was a racquet spinner ... and the top edge alternated close to 50% … I would get close to same hours. But then ... no mid-life fresh string moment.
Also, how do you guys vibrate the strings? I have found that vibrating with different articles leads to different tension readings.
