A flash in-between primary flashes with different brightness (or other
characteristica) is usually not an indication of a half period.

They may even be slightly offset from the mid-point, if the two surfaces on
opposite sides are not exactly parallell.
More than two surfaces can also be involved.

The effect can be most easily be detected if the flash times (NOT the flash
intervals) are plotted as offsets from integer multiples of the presumed
period, with my Synodic program, or using the modulus function in Excel.

Attached (?) is an example with one well-timed main series with 10.688 s
period, but two secondary, less accurate series, about 2.2 s before and 3.3
s after the main flashes.
