I suspected that, thanks for confirming it.

I want to be sure I understand this. I meant that where I expected each
group of 5 frames to consist of three of the same then two of the same,
sometimes I see this pattern disintegrate into several pairs of similar
frames, breaking up the "3 then 2" pattern. Do you mean that it's possible
for repeated frames to occur randomly in groups of either 2 or 3? Thanks
again.
