Looking at the planet rankings, things look pretty much fine to me. Yeah, on average planets had about 40% of their score in XP (in the top 10, top 100 and top 300), but that's a far cry from what it looks like in
real XP rounds. It means that while XP was strong, you were unlikely to do well if you weren't
also building your value. Perhaps even that people were building value and getting XP more or less as a nice side effect?
I also looked at the averages over the course of the round, which yielded
this graph. Nothing shocking there either, but it does show it wasn't just people XPing the last 100 ticks or a final boost. The weird peak/nadir for the top 10 (and
only the top 10) in the 600s is pretty weird, though.
Overall, I see no reason for panic.
