Dude, there are no failures only results. 22:40 is better than a majority of the population could manage. Most couldn't do 100 Burpees in 24 hours.
I love this challenge. It's intense, it's dynamic, make me breathe harder than anything, sweat pours off me, and it has a simple goal, beat your last time. I'm going for a sub-10 minute and I'll be happy. I'm going to be so happy when I reach that goal. If you can do 10 Burpees a minute for 10 minutes, you're in shape, pure and simple, no debate.
Great exercise and great effort. Keep at it. :D
