Measuring turntable speed

Is your graph more accurate  than a wow and flutter meter???  Been playing with a test record and wow and flutter app lately.

Thanks

Optimize thanks for the information.  I have a Phoenix roadrunner for the speed which goes out to 33.333.  I have been interested, in the different turntables I have been building, to see if you can see the difference between a 35 lb platter vs 55 pounder.  Also different bearings I have been playing with.  

The roadrunner take one trigger per revolution then does the math.  But like you say what goes on for the 2 seconds.  

It would be nice to know how the software or machine samples the revolution and how accurate it really is.

I need to experiment more to see what make changes in the readings.  
 
Thanks again

Different belts and tension can affect wow and flutter/ speed stability.  You can watch the road runner pick that up to a certain degree.

Enjoy the ride

Just wondering how many turntables you have built??  How many platters of various weights and materials have you tried on the same turntable??  And how about motors and controllers???

Also they use heavy platters with small motors.  But the bearing could be a issue.

Just wondering how you reached a conclusion on what is trivial in audio???
