We usually have large separation when we have reflected bows. However,
it would seem to be that if this phenomenon is caused by nonspherical
drops, we would require stronger nonsphericity to get larger
separation. To get stronger deformation, you need larger drops, and
those are also much more likely to oscillate. Slightly nonspherical
drops are more likely to be similarly deformed and thus cause a
distict phenomenon.
