Very interesting. One of our colleagues/friends also proposed this one! :) Will take this as inputs, if we change it. Thanks!

Another vote for "surprisingly". Although "frustratingly" is kind of fun because it's so weird...just too negative. If you want to keep a provocative adverb, maybe "oddly" or "weirdly" would be fun too...not normal, but not so negative.

I like it. Nothing is better than a pleasant surprise. You win this one dang!!
