I've just taken delivery of an Alpha Revo4000 lockout machine. I had been using a Silent Partner eStringer w/ flying clamps. The quality of the Alpha is awesome. My question is on the tensioner. I typically use one of those spring tension gauges to check the tension after stringing for reference only - to determine if the racquet has lost tension to the point where I need to restring. However, with the Silent Partner if I strung at 68lbs. the tension gauge was pretty close to 68. Now, in using the lockout on the Revo if I string at 68 the tension gauge reads about 58lbs. I talked to Alpha and they said try bumping up tension by as much as 10% as compared to constant pull. So I tried it last night, strung my Pure Drive Plus at 76lbs on the lockout and it came up 63 on the tension gauge. Is there something I'm missing, doing wrong, not taking into account? I just find it hard to believe that a constant pull machine would make that much difference. I went away from the SP machine because of the flying clamps and I really grew to hate the tension head on it. The alpha is great build quality, love the clamps, it's easy to use - but this tension thing might get to me. Thanks!
