Right. That's a better way of saying it. The paper doesn't describe
the numerical techniques well enough to critique them. There is some
sort of linear component to the fit, but it doesn't appear to
correspond to the tidal slowing term. Perhaps clues are buried in the
references.

Likely lack of DC removal and/or deficient windowing before running
the FFT I suspect they used.

Timekeeping is one of those narrow disciplines where peer review
implies small number statistics. So this paper joins others of
suspect validity such as:

To be more convincing I'd like to see what happens to their
model if they used 5, 10, or 15 terms instead of 17. Plotting
the quality of fit against the number of terms used would be
revealing.
Also I'd like to see what happens to their projections if they
used a shorter or longer range of dates.

Look at figure 4, the appropriate caption would have been "Our model
is bunk".
Apart from forcing some poor undergraduates though a lot of math,

Notice the detail that of the only projected leap second in the period
2006-2024, it was predicted to 2008. This matches the achieved pattern
so far.
