Hi Alan,
2 Chronicles 36:20 is a direct statement that this prophecy [Jeremiah 25:10-12] was fulfilled when the "royalty of Persia" came to power and the Jews no longer were servants to the king of Babylon. Therefore, the period of 70 years foretold by Jeremiah ended when the Persians conquered Babylon, and the king of Babylon was punished, in 539 B.C.
Yes, that much was clear to me when I answered your question about the year that the royalty of Persia began to reign.
However, I wondered how the WTS reconciled this and so did a bit of research. The book Babylon the Great Has Fallen! - God's Kingdom Rules!, 1963, pp.364-366 had this to say:
In calculating the "first year of Cyrus the king of Persia," we must faithfully proceed according to the inspired Word of Jehovah God. We accept from secular historians the year 539 B.C. as a fixed date, marking the downfall of Babylon, the Third World Power. But the Bible introduces, immediately after the fall of Babylon in that year of 539 B.C., the reign at Babylon of Darius the Mede. (Daniel 5:30, 31) The prophet Daniel, who was there at Babylon, speaks of the "first year of Darius the son of Ahasuerus of the seed of the Medes, who had been made king over the kingdom of the Chaldeans." (Daniel 9:1; 11:1; 6:1, 6, 9, 25, 28) In harmony with the Bible we must accept at least one year, with possibly part of a second year, for King Darius the Mede. Hence, at the earliest, the first year of King Cyrus the Persian may not have begun till late in the year 538 B.C. to extend over into the following year of 537 B.C.
Cyrus decree was evidently not issued before the first year of Darius the Mede was disposed of and Cyrus became sole ruler of Babylon. The Bible does not say that it was in the first year of the reign of King Darius the Mede that Cyrus issued his decree, nor does the Bible say that Jerusalem's desolation came to an end in the first year of King Darius' reign. It was in the first year of his reign that the prophet Daniel studied Jeremiah's prophecy concerning Jerusalem's desolation, and this study on Daniel's part must have been before Cyrus issued his decree in his own name in his own first year of his reign aside from Darius the Mede. Daniel 9:1-18.
In view of the time that it took the homesick Jews to get ready and then make the trek back to Judah and Jerusalem, the decree of Cyrus must have been made toward the close of winter and the beginning of spring of 537 B.C.

On page 404 of Volume 4, The Jewish Encyclopedia
says: "Cyrus always conformed to the traditions of the thrones he usurped, and, together with his son Cambyses, rendered homage to the native deities. On the first day of the year, Nisan 1 (March 20), 538, in conformity with Babylonian custom, he grasped the hands of the golden statue of Bel-Marduk, and thus became consecrated as monarch. From this ceremony dates the first year of his reign as King of Babylon, King of all the Lands." Cyrus thus had himself proclaimed as king of Babylon and as the legitimate successor to the deposed King Nabonidus. By doing this he did not have to reconquer the Babylonian Empire. Babylon's foreign possessions, Syria, Phoenicia, Palestine and the borderlands of the desert, all came to be tributary to Cyrus.See The Westminster Historical Atlas to the Bible (1956), page 75, paragraph 3.If we proceed according to the cuneiform inscriptions, rather than the Bible, we have to take the position that Darius the Mede and Cyrus the Persian reigned concurrently for a time. According to this, the accession year (an incomplete lunar year) of Cyrus as king of Babylon began on October 23 of 539 B.C.E., when he entered the city (by day) after its capture by his troops. Hence his first regnal year (a full lunar year) began on Nisan 1 of 538 B.C.E., or on March 17/18 of 538 B.C.E., Gregorian time.
The cuneiform tablet entitled "Strassmaier, Cyrus No. 11" mentions Cyrus' first regnal year. By this tablet it is calculated that this year began March 17/18, 538 B.C.E., and it ended on March 4/5 of 537 B.C.E., Gregorian time. So Cyrus' second regnal year began the next day, on March 5/6, 537 B.C.E. In this case Cyrus decree must have been made before this latter date that is, late in the year 538 or early in 537 B.C.E. See pages 14, 29 of
Babylonian Chronology 626 B.C. - A.D.75, edition of 1956, by Parker and Dubberstein.
Now if I had remembered that (I last studied the Babylon book when I was a schoolboy) I would not have been quite as dogmatic that the year "the royalty of Persia [i.e. Cyrus] began to reign" was 539. The Hebrew word meaning "began to reign" is malak and means to become a king or to be made a king and so I guess it could refer to the regnal year.
Alas, Alan, the spirit is willing but the flesh is weak. It's late now so I will try to complete my reply tomorrow and address the rest of your argument then.
Best wishes,
Earnest
