Howard Johnson Replication Tube Claim

That's great, LR! I am surprised that it worked so well, actually. But I thought surely it would work better at the low speed end than the high...I'm a bit confused about that part. Is there something I can do to improve the low-rpm resolution, or in general?
But still, that's pretty impressive and should answer the objections about whether your analysis can be applied confidently to Mylow's vids. Clearly it can.

TK,
Good job with the new video, the quality was significantly improved
Small adjustments should fix the situation in low RPM ... at high RPM is a matter of quality and frames / sec.
Thanks for taking the time to do this small validation.

Edit: the sensor takes a lot of data per second when it is in an area of low RPM it starts to distinguish all the shades of gray and data becomes less clear for the conversion program that produce the acceleration curve.

Yes, you are right, that's the point of calibration and validity testing. If you run your video analysis on my video, and your graph looks nothing like the one I recorded "live" with a calibrated instrument, then you can bet it won't work on other random vids either. But,say, your graph looks like mine only stretched and skewed. Then a correction might be applied to your data or method to make it usable on other videos.
So, anyway, there's a target, and the data taken "live" are there too. I'm sorry I couldn't do it on the "real McCoy" but you'll have to take that up with Mylow.

No I am not taking it up with Mylow,  you and your friend are quoting data from your "calibrated environment" under what parameters are you conducting your experiments ?

Let me guess you have no idea ?

@Yucca and Toukoqouko: Beautiful!!

Video was changed to private . . effectively removed from public view ..

Why would he do that after he obviously put a lot of work into it ?

Threatened .. bad data .. anyone ?

I think some of this video analysis stuff is darn good!

If you look at the one below you can actually see, just before the green line, the decline just before it enters the stator area and then the initial acceleration as it starts in, then the little dip about in the midpoint of the rotor magnets then the large kick at the end where all the work is done!

You can tell it's not level and the large kick at the end is doing most of the work because of the larger rounded area at the top of the peak where it is pushing it up a slope.

It then slows down quickly as it continues to climb the grade and then the final acceleration as it swings down the grade and back toward the stator area.
