Gaps between AC dates stay the same to not mess up the timeline
subtract the date you want to find out from the next date and record the difference
the number measures the number of revolutions until the next date

the AC date for the start of Hyperborean Path is correct

The gap between the last two correct AC dates (first signs of Aureiyx civilization to start of Hyperborean Path) is 27913.3000002 Tartarusian revolutions, or 18799.9227927 earth years. This spans the majority of the timeline, the two dates before it being the formation of the solar system and the materialization of Synapse.

What is required to fix AC is to move it from 8 million so that the first currently incorrect date (first signs of Tartarusian civilization) is after 7,423,722,086.7, and the last incorrect date (Camelli secession) is before 7,423,750,000. This block of incorrect dates spans 85377 Tartarusian revolutions. This cannot fit into the previously explained gap of 27913.3000002 Tartarusian revolutions. The last two correct AC dates CANNOT be changed to make room. Seeing as how human civilization spans approximately 17817.0731707 Tartarusian revolutions (12000 earth years), the logical course of action is the squishing of this block of incorrect dates.
