In my opinion, you DO have a misconception about our relative skills: I don't feel I have played better in any way, especially in this particular game. Level, as good as it sounds, does not really reflect skills.
As far as I can remember, I have never seen a treasure-oriented strategy ends up with 4 Provinces in 10 turns before. That is really remarkable for me. And I cannot help but wonder maybe there is more to it than pure luck. I don't know, judging from the discussion here maybe not so much; I'll keep an eye on these cards though.
