Turntable speed accuracy

From what I can see and read about the Speednic......it seems no different to a Kab strobe?
Can anyone explain to me how the Speednic competes in any way with the Timeline?

I downloaded the iPhone app and did some testing. The same test record that I used before also has a track with 3150Hz. As I mentioned before, I measured considerable runout in my test record which by itself causes some audible Wow when playing constant frequency test tones. The center hole of this test record has a slight amount of play on my tt spindle. After much patient work to minimize the record runout I got the following measurements: Mean Freq: 3151.3, Raw Frequency: -0.22%/+0.24% relative, -7.0Hz/+7.4Hz absolute. Lowpass Filtered Frequency: -0.02%/+0.01% relative, -0.5Hz/+0.5Hz absolute. I'm guessing that the filtered values subtract out the record runout. The reason I conclude that is as I meticulously adjusted the record on the platter to minimize runout, I had raw numbers as high as -9.8/+10.7Hz while the filtered values never exceeded 0.03%.
Another observation: The original Mean Freq was 3155.6Hz based on my setting using the strobe disc. I adjusted speed down and can certainly work some more to dial it in at precisely 3150Hz. The other observation is that holding the iPhone while taking the measurement adds more error. It is sensitive enough to pick up hand movements. I set the phone on a table about 1 meter away from the front of one speaker.
So how does my humble BD table compare to some others?
btw- I have a record clamp. So I adjusted the record relative to the spindle and then clamped the record down.

It seems like none of us read each other's posts, except Raul and DT, so that they can reach immediate disagreement. A century ago an American writer named Ambrose Bierce defined "conversation" as a social interaction wherein I wait for you to finish talking so I can say what I want to say. In any case re turntables, DT is right. The first job of a tt is to get speed right. Raul used to argue that a phono stage that does not do riaa within 0.1 db is fatally flawed. You can't have it both ways, Raul.

Dear Lewm, disagree. I think they read the posts but they understand it in a different way as you, me or others do.
This is not because they not only have a more sensitive scope but maybe they have a more sensitive feeling too when reading each other`s post.

Nevertheless I do think in this topic we are all not far away from each other. We all agree that accurate speed is an important condition or precondition for enabeling a good sound quality.

Of course there are other factors having also an impact on good sound quality, the bearings quality (e.g. air based or other quality attributes), the motor´s quality (maybe also fly wheel or more motors), the platter`s quality (material, weight, air lips) the belt, thread or idler wheel`s quality, and last not least the interference and the implementation of all these turntable parts. Enough stuff for some more threads...

I found the owners manual online for Adjust+ and some reviews. As I surmised the low pass filter is set for 0.56Hz to eliminate record runout. I was considering drilling the center hole out a few tenths of a millimeter on my test record, but I began imagining what a catastrophe that would be me loose with a hand drill with one of my precious records. Fortunately this iPhone app cancels out the record runout for you. Pretty cool app.
Regarding the tt bearing: I do my own maintenance on my tt. Periodically I breakdown the tt and clean the main bearing. I re-lubed last time with a synthetic grease. I think it made the tt sound better. Anyone else had that experience? I have never touched the motor.
