Inactivity leak protocoll

Hey guys, I’ve had this question on the ethstaker sub, but its quite inactive.

If the protocoll is active and i happen to have a couple missed attestation at the same time for some reason (electricity outage, or update installion) do i get pushed into the 1/3 that is getting punished? How is the punishment calculated inbetween the inactives meanwhile the active validators are taking back the 2/3 majority?

Thank you for the help guys.
