the video title is more promising than the content actually delivers. but the testing method mentioned in the video is quite interesting, maybe be can do some community benchmarks.

my result now is 15. though i get in stress after 10... so my co2 acceptance is garbage.

test is as follows:
- 3x (breath in 3secs, breath out 3secs)
- breath in deep and strong until full
- breath out continouse as slow and long as possible, AND MEASURE SECONDS WHILE DOING THIS

< 20 sec = bad
20-40 sec = average
40+ sec = above average

after multiple tries i now reached 22!!!
