Wow/Flutter and Speed Stability

I'm planning to purchase the Feickert Adjust+ to measure wow and flutter of my TT and as many other TT's that I can access to try and create some correlation of speed stability to drive system, motor type, belt vs thread vs tape, tension, and platter weight. Of course I will try various tests on my own TT and am interested to put some measurements behind the observations.

In my opinion, speed stability and pitch stability as a result, are very noticeable sonically and comes across as bass weight and definition, a large expansive soundstage, a lively sense of clarity, and explosive dynamics.

In my opinion, these characteristics coming from speed stability can greatly outweigh differences in tonearms and cartidges.

Have any of you used this software or other method on your TT's? Can you share your measurements or observations?

A good tool that I have acquired recently is the Sutherland Timeline. Look on YouTube, and you'll see how it works. There is a demo there. Anyway, it is a great item, especially if you set up turntables frequently.

I don't sell it, but I do like it.

Doug,
It has been changed since the first version, and while it can't catch sudden issues like stylus effect, it can show things like drift, stylus influence on the record, etc., in a more general sort of way that is way more accurate than the typical strobe disc affair at greater than two parts per million. I was actually surprised at its response on certain turntables that I tried with it.

What I would like to see is a strobe disc so large that it almost hits the tonearm base. An extension like that would also be more accurate than the typical disc.
