I decided to post this in the general thread instead of Stringway users thread. Perhaps it is useful to some one who is not yet an SW user. First of all apologies for loosely commenting on this on some thread before. I double checked the pulling accuracy of ML100 automatic constant pull machine and results are not that I stated before here. Now I took the measurements many times, from different attach points of the scale and repeated. Stringway claims that the pulling tension is not dependent on the angle of the weight lever. I wanted to believe this and enjoy stringing with "most accurate machine in the world". I set the tension to 25kg and checked the tension first the lever in quite down position - not "flooring the lever however. The tension read 24,45kg. Not too far from 25kg but not 25kg. Then I checked the tension with lever on clearly higher position. Now the reading was 26,93kg. The difference between positions is about 2,5kg. Most of the time when stringing racquets you end up using more or less same angle and in my case it is more at high than low. So obviously I am tensioning little higher than what I believed to. This explains why I get usually higher tension when measured with Racquettune than my set tension is. Now I don't know if this is a big problem for me. At least I know how it is. But naturally it annoys a bit when you don't have what you believed you had. Pics of the measurements can be seen here: https://plus.google.com/photos/103578011377325984720/albums/5955521540171399617 The angle of lever is bit hard to see but gives you the idea however.
