Your tabulation is shonky because it is easily seen that the Tishri, the seventh month = September/October could not have fallen in 538 but only occurs in 537 BCE for the first year of Cyrus from Nisan, 538 to Nisan 537 BCE. For that crucial year to have fallen in 538 then you have in the accession year of Cyrus not his first year.
Your silly and stupid tabulation does not work because you 538, 537 and 536 beginning from January instead of March-April as the beginning of the year so you have replicated an error of three months.
You should sit down and do the tabulation again and do not drink any XXXX whilst attempting this simple task.
