I'll wait until I see data points, but I struggle to imagine Marriott IT correctly giving out 12 elite nights for a 5-night award + 1 paid night tagged on reservation, when under normal (no promo) circumstances you'd either get: 0 elite nights, 1 elite night or 5 elite nights (until you chase somebody down to fix it).
