Hello, Turanclancath:)
Yes; the ( Septuagint ) supposedly gives that "215 years in Canaan and 215 years in Egypt stay" a bit of a poke at the dates. I favor the TAnkah, which says straight out: "Now Israel was in Egypt 430 years, to the very day" (Ex. 12: 40) When I added up the 'begats'--sorry, that's what I call them for the lack of a better term--they go straight to our ("

I like more 1447 or 1464") as figured from the time Israel (Jacob) entered Egypt, ca. 1894BC.
And yes; I agree again about placing Amenophis III within "Circa 1383/ 1345."
Moses and the group headed out a century earlier--under the elder Thutmoses (others might want to reference our earlier posts).
That dating, of course explains the Amarna Letters about the HAbiru who had been attacking. (They had been doing so, under their judges for almost 60 years, by that time... By Ju. 2:16 the Judges had become the commanders--perhaps the very ones Abdu Hepa, Lab'ayu, etc. complained of!
By the time of the First Temple ca. 980-967...they had "kings" but at the time of Amenhotep III and Akhenaten, their leaders would have those Judges (according to the 'begat' dates)--
Although Moses installed the Judges early on (Ex. 18), by the time of Ehud (Ju. 3:12) old Amenhotep III was near death. This corresoponds to the Hittite-Anatolian wars that caused plague (Tulamaria)--suddenly, the 'begats' show that is the year Joshua died, Amenhotep III, and (as many sources say) "many royal household members"; including Akhenaten's daughter. The very tail end of the Amarna Tablets then, corresponds to the Moabite power mentioned in Judges 3:14.
Egypt, during Amarna, had not only lost their vassals (gained by Thutmose III, Amenhotep II and Thutmose IV) to the Habiru, but the Moabites, as well!
So, where does the Merenphtah stele fit? Right after Deborah's song about the kings that came to fight at Megiddo ('Liadees begat date' ca. 1251--Merenptah's father, Ramesses II's war). Jud. 5:19
Ju. 5:31: "and then the land had peace (stability??) for 40 years."
...da da...enter Merenptah, his 13th (?) son.
Of course all of our stuff is 'speculative' but, again I say: there is some reason the OC is changing to the NC...and we're meant to be a part of this for some reason. True, we weren't there, so we can't really know all the details but let's keep at it...often times the past looks better than the present.
Take care, Lia
