First of I'll venture that it was a elbow in spoke (50/50 odds on that so no genius involved). IME, of the 4 types, elbow in/out & left and right flange, I've found the elbow in left side spoke the most likely to break.
We all have our pet theories about spoke breakage, but when it happens this soon, I prefer to call it a fluke and let what happens later drive my process. If no other spokes brak for a long while it truly was a fluke. OTOH, if more spokes break and.or the interval gets progressively shorter, then I start searching for possible answers.
