An interesting step toward understanding the substantial brightness variations seen from JWST came from
Peter Plavchan at George Mason University. He reported a 3-hour light curve which had remarkable symmetry.
where the timing and amplitude of four peaks were almost perfectly mirrored after a brightness minimum. He shows a graph 
with the time overlay in

With a little imagination, a similar pattern centered between two peaks may be there in the earlier light curve from 
the University of Hertfordshire:

I haven’t yet followed it for so long - this may be incentive.
