From what I understand.

0.5 SEV% is about the point that the human body can notice the effects of CO2 i.e. slight headache, dizzyness..., ect and this is the point as previously mentioned is considered "breakthrough" as far as the US Navy is concerned.

2 SEV% is a decent headache

4+ SEV% prolong exposure can cause unconciousness

10 SEV% can instantly cause unconciousness

Jeff Bozanic's book Mastering Rebreathers talks about CO2 exposure.
