Happened during a 50 round attempt. I'm starting to get slightly more consistent, but I've also been resetting a lot more. Just don't feel like I'm getting the best luck; I know I have one really good run in there somewhere, and my SoB being almost 4 minutes ahead of my 50R PB is proof of that.

Side note, my SoB through 20 is under 6 minutes, so I know there's time there too.
