Correcting drifting with Sutherland Timeline

Just had a couple of days setting t/t speed using my newest purchase - the Sutherland Timeline Laser timing tool and thought I would share how good it is, once I got my head around how best to set-up and use it.
The supplied one page instructions are vague to say the least and it took me time to settle on which wall I was looking at to see the laser projection settle.
But once I got that fixed, it was easy to make minute adjustments on the VPI SDS and easy to correct drift and pitch. I found that using a sheet of graph paper 'blue-tacked' onto the wall behind.
Astonishing to see the effect that the addition of the periphery ring clamp to HRX platter had on RPM. Never before have I been able to recognise and so accurately use adjustment of SDS khz and hear the pitch snap in to focus.

If this device is as accurate as we are being told, I suspect that in many cases we are going to discover that our motor controllers (even the signature and reference versions that we paid a lot of money for!) are simply not up to the task of setting and holding a fully accurate speed of rotation, even with records of the same weight.
So my question is: on the basis of your experience so far do you have any reason for thinking that the Timeline is simply too accurate for the job?
