Well it was Daniel haha, but I agree with that if you feel good. Sometimes I actually do them 20 minutes before my actual level workout though because I have the most energy then. And sometimes I "skip" a level to train moves while still using my muscles (things like front lever, back lever, etc). Sometimes my muscles are completely exhausted during/after the burnout so I probably won't do the best on them. It depends on the day I guess and how you feel, just find what suits you the best.
