Timeline Calculator

I just made a calculator in Excel for the Sutherland Timeline. You enter the distance to the wall and the laser deviation per revolution and it gives you the circumference of the virtual circle that the laser travels, the speed error of your platter in percent, the RPM your platter is off by, and the actual RPM of your platter. It can also tell you how many Hz a given frequency is off by.

Let me know if you would like to try it out!

The Timeline appears to be a very accurate and precise instrument. Perhaps too accurate for measuring turntable speed as you may be chasing an impossible standard. Once you dial in your table for perfect speed, is the speed accuracy repeatable and constant over a period time when taking in consideration temperature changes, power changes, humidity changes etc. Is the Timeline a cure or a curse?

PS- Ketchup, nice work on the calculator
