Far less controversial than the other one, anyway...
One thing I've realised I missed off the populator discussion:
Thargoids! In 1.77 one gets added to the initial system about 6% of the time. (10% or 3%, in fact, depending on whether the original inhabitants of the system before changes via planetinfo.plist or script were Colonials or not)
What I'm considering is having two types of Thargoid appearances (they'll both use the "thargoid" role to determine which ships are used):
thargoid-scout: a single warship is added, makes its way to the space lanes, and attacks. They won't appear near the normal witchpoint, or it'll be too hard to believe that the witchbuoy has survived this long. These ships can appear anywhere on something similar to the current frequency, but are a little more frequent in systems with a lower hub count.
thargoid-strike: a raiding party of thargoid warships is very rarely added to systems (once every few days), attacking strategic targets (stations, large freighters, etc.). The size of the party depends on whether the system is a bottleneck [1].
No: 1-2 ships. Barely distinguishable from scouts
Yes: 4-5 ships. Not something you'd want to meet early on, but if they appear every few days, considering that most systems aren't bottlenecks you'll probably only see them once every hundred trips at most.
Double: 10-15 ships. Major emergency, but double bottlenecks are very rare (I think Anbeen and Edorte are the only ones in G1. Other charts have more, but still not that many). Unless you're trying to hunt these down, seeing one will be a very rare occurrence.
Triple: the formula I used to get the previous numbers gives 30-50 ships. There are only two triple bottleneck systems (Esgelage and Erusat), and you'd have to visit them perhaps fifty times before you actually saw this invasion fleet, so it doesn't seem worth special-casing this down to a more sensible number. There'll be someone who actually wants to hunt them, I'm sure.
[1] To see if a system is a bottleneck, consider only the systems within 7LY of the system. Then remove the original system. If the remaining systems are split into two disconnected groups, then it's a bottleneck. Lave is a bottleneck (groups "Zaonce" and "everything else"). They're really obvious on the map and not straightforward to describe formally... Double bottlenecks split into three disconnected groups.
