Even then, the x ms faster on day... is a calculated expectation, we can take that calculation and adjust for the entire year and the overall change in earths rotational speed is much much smaller. Individual variations are much higher and even then barely noticeable without excessive measurement that has almost zero value outside of intent to be overly precise.
It's like calculating pi to the millionth digit, it has effectively no meaning outside of the ability to calculate pi. Absolutely no engineering task is improved by calculating pi out to 2 million digits vs 1 million.
