@salfaro they have mentioned that 90-100 is master-level (or something similar), and we have seen ppl with stats that break 100 and even over 110, meaning that 80 is relatively low and should probably be compared to the best few in a country as opposed to the best historically (though still likely to make a name for themselves in the annals of history depending on circumstances).
So for ambition, I figure that doesn't even qualify the person as high enough ambition to revolutionize society as a whole (like those that labored until women got right to vote, or led a revolt that took down the entire government, sometimes even inventing their own). And likely also not high enough to break out of cultural norms for things that doesn't matter the most to her (hence why I mentioned he might still get a mistress if he feeds her ambition with political standing and lets her focus on that instead of romance).
tl;dr I didn't call it 'low', I called it "low enough". Low enough to still have room for that harem which isekai mangas require, to be exact.
