Language is best as a conversation, a duologue. As GBS put it "Two countries separated by a common language" - but posts, and monologues we don't have the same querying option, so assume.

In Europe (but not the UK) eventually is taken to mean it depends on events. In UK English, and I assume USeeze, it mean sometime. Imagine the fun and games in contracts!

Quite good we take to mean nothing special (reliable, average, no sparkle, unvoiced caveats). Whereas good is more praiseworthy, and very good is one step below excellent.
