So the CO2 level peaked and then slowly dropped. It was all from the same event and not discreet events as you are trying to pretend

It was well above modern levels from near the beginning of Earth's atmosphere through every geological period until Paleogene, so for billions of years, even billions of years if your only (reasonably) counting from the time that the atmosphere became mostly nitrogen and oxygen. Including the Permian period for many millions of years before the Permian-Triasic extiction event (which to the extent it was about greenhouse gases was not mostly about CO2 anyway).
