I just certified for L1. 4 weeks ago. My 4 inch dual deploy Fusion apogees at about 7 seconds. I drill for a 10 second backup. (4 seconds off 14). Today is the first time I could hear the backup charge. It was directly overhead and I counted about 3 seconds. Used a white lightning, a red line, today another white liightning, and 2 weeks from now a blue thunder.
