Yes, it's me, around the time I stopped last. I'm restarting now, trying to get as much specific advice as I can, and I am addressing the safety rail issue.
And my video freaks me out too. It wasn't that scary at the time, as the bar was supported from crushing me by my strength, and it came down in a fairly controlled manner. I knew I could hold it there a while, and could dump the plates. The lying there didn't feel as long as it was.
