I pasted the entire 22nd Amendment into my reply to this post. The "trigger" isn't the numerical value of 8 years total, it's the numerical value great than 2 years served.
No person shall be elected to the office of the President more than twice, and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once.
It would be interesting to see the Supreme Court try to enforce that on the person who has the ability to suspend habeas corpus and have them all arrested.
You are correct and to atone for this mistake I’ll ritualistically slaughter a pig and take one strip of bacon from it, leaving the rest for nature to have her way with it.
