Jane, we've had expansions that have skipped and it's either down to expanding population being too small for a large population or a large population ignoring a small population and going for a large population. We have also had a double expansion where a medium population expanded to 2 small populations.
I'd also add that some systems may be reserved and that's why they are missed, but missing so many? That is weird.
