I didn't say "exactly 400-430 years". Nonetheless, I've concluded that that 400-430 years again applied to Jews from the time of the Alhambra Decree—when a disgusting practice of throwing Jews whom paid ship captains overboard happened—to either the time of the Dreyfus Affair—which began with his May 1892 arrest—or May 6, 1922, when strokes incapacitated Lenin and effected that Stalin would become Lenin's successor. At those points, Jews knew that making aliyah would be a wise action:
This time, the Moseses were Herzl and the B'nei Akiva branch of HaPoel HaMizrachi—which was founded in Yisra'el 22 days after Lenin's stroke. Granted that both events occurred in Iyar instead of Nisan in the respective years, and that the Alhambra Decree happened in Adar II of 5251—right before Rosh HaShanah 5252. Still, right in the middle of Adar—the month in which Hadasah saved Persian Jewry from Haman, whom made a decree of ethnocidal murder in Nisan—and Iyar—in which Yisra'el was refounded—is Nisan:
By the way, a generation is 20 years, though generations and lifespans were usually longer back then (cf. the passage from Exodus 6 below. The 120-year life expectancy that was declared in the time of the Flood, by the way, began when Moses died.):
Also, Iyar is the second month—again, when the Dreyfus Affair began and Lenin had his stroke—and Iyar was the time for Zionism to begin—after all, Adar and Nisan were the months that culminated the buildup to the Dreyfus Affair and the beginning of Stalinization. Remember, by the way, that the 12 sons of Ya'akov and others had to pass away before slavery in Egypt began:
If you don't believe me, look at both Tanakh and at these Google searches, and peruse the sources that you find:
As I concluded, then, 400-430 years on a literal level and on parallel levels have applied to Sephardi, Ashkenazi, Mizrahi, and other Jews to this day.
"13 And He said unto Abram: 'Know of a surety that thy seed shall be a stranger in a land that is not theirs, and shall serve them; and they shall afflict them four hundred years; 14 and also that nation, whom they shall serve, will I judge; and afterward shall they come out with great substance. 15 But thou shalt go to thy fathers in peace; thou shalt be buried in a good old age. 16 And in the fourth generation they shall come back hither; for the iniquity of the Amorite is not yet full.'"

"And the LORD spoke unto Moses and Aaron in the land of Egypt, saying: 2 'This month shall be unto you the beginning of months; it shall be the first month of the year to you[']."
By the way, a generation is 20 years, though generations and lifespans were usually longer back then (cf. the passage from Exodus 6 below. The 120-year life expectancy that was declared in the time of the Flood, by the way, began when Moses died.):
"And the LORD spoke unto Moses in the wilderness of Sinai, in the tent of meeting, on the first day of the second month, in the second year after they were come out of the land of Egypt, saying: 2 'Take ye the sum of all the congregation of the children of Israel, by their families, by their fathers' houses, according to the number of names, every male, by their polls; 3 from twenty years old and upward, all that are able to go forth to war in Israel: ye shall number them by their hosts, even thou and Aaron. 4 And with you there shall be a man of every tribe, every one head of his fathers' house.[']"
Also, Iyar is the second month—again, when the Dreyfus Affair began and Lenin had his stroke—and Iyar was the time for Zionism to begin—after all, Adar and Nisan were the months that culminated the buildup to the Dreyfus Affair and the beginning of Stalinization. Remember, by the way, that the 12 sons of Ya'akov and others had to pass away before slavery in Egypt began:
"1 Now these are the names of the sons of Israel, who came into Egypt with Jacob; every man came with his household: 2 Reuben, Simeon, Levi, and Judah; 3 Issachar, Zebulun, and Benjamin; 4Dan and Naphtali, Gad and Asher. 5 And all the souls that came out of the loins of Jacob were seventy souls; and Joseph was in Egypt already. 6 And Joseph died, and all his brethren, and all that generation. 7 And the children of Israel were fruitful, and increased abundantly, and multiplied, and waxed exceeding mighty; and the land was filled with them. {P}"
"These are the families of Simeon. 16 And these are the names of the sons of Levi according to their generations: Gershon and Kohath, and Merari. And the years of the life of Levi were a hundred thirty and seven years. 17 The sons of Gershon: Libni and Shimei, according to their families. 18 And the sons of Kohath: Amram, and Izhar, and Hebron, and Uzziel. And the years of the life of Kohath were a hundred thirty and three years. 19 And the sons of Merari: Mahli and Mushi. These are the families of the Levites according to their generations. 20 And Amram took him Jochebed his father's sister to wife; and she bore him Aaron and Moses. And the years of the life of Amram were a hundred and thirty and seven years. 21 And the sons of Izhar: Korah, and Nepheg, and Zichri. 22 And the sons of Uzziel: Mishael, and Elzaphan, and Sithri. 23 And Aaron took him Elisheba, the daughter of Amminadab, the sister of Nahshon, to wife; and she bore him Nadab and Abihu, Eleazar and Ithamar. 24 And the sons of Korah: Assir, and Elkanah, and Abiasaph; these are the families of the Korahites. 25 And Eleazar Aaron's son took him one of the daughters of Putiel to wife; and she bore him Phinehas. These are the heads of the fathers' houses of the Levites according to their families."So, a generation's life expectancy by that point—at least among HaB'nei Levi—was 137 years. So, go for 120*4 and 137 * 4, and you get 480 and 548 years. The average is 514 years, and enough below 514 years had passed between 1492-1892 and 1492-1922. Also consider this: the max life expectancy for those whom the Spirit is with (cf. Genesis 6:3) will someday be 100 years, and is pretty much the max life expectancy that by now—which is why centenarians and those whom are older than centenarians are celebrated and make the news:
"19 And I will rejoice in Jerusalem, and joy in My people; and the voice of weeping shall be no more heard in her, nor the voice of crying. 20 There shall be no more thence an infant of days, nor an old man, that hath not filled his days; for the youngest shall die a hundred years old, and the sinner being a hundred years old shall be accursed"We can see here that the sinner will die at 100 years and that the redeemed will go on to live past 100 years. By the way, 25 is close enough to 20; and that's when the brain reaches its full-development point. So, generations in terms of biology could really be argued to begin at 25 at max and 20 at minimum.
