periodicity

Do you mean that the periodicity is too consistent to support the theory of an orbiting body, because an orbiting body would have a less consistent orbit?

Instead of one day noticing that a picture is corrupted or the computer won't boot, periodicity scrubs will detect corruption before it's too late.

In general, ODE solvers can't be expected to maintain invariants of the ODE system, such as periodicity.

The supposed impact is merely a data point that could be used to interpret Earth impact periodicity.

Currently visiting, this book orbits in and out of the rotation with a cometary periodicity.

This might only add evidence to suggest that there is periodicity to Earth impacts.

Say, observing the periodicity of star movement was important, but the gravitic theory built on that to produce even more valuable information.

As I understand it the idea of periodicity for impacts is debated and is not statistically conclusive.

There are other hypothesizes besides Nemesis to explain the supposed periodicity of impacts.

Instead, I'd recommend just graphing average usage over a year, a month, and a week periodicity and eyeballing it.

I'd expect the prorating to spread the dates evenly across the decade precisely to avoid this kind of periodicity.

For years, 'til his last day, he fought against quasi-periodicity in crystals...

There's a couple major misrepresentations here; while 450,000 is an often-stated average, its important to note that there is no evidence of periodicity, so the idea that the planet would be "overdue" for a reversal is misguided.
