I think dual splits are not as rare as one might think, especially for people "driven" to be high achievers, while tri splits are a bit more unique (and in my "theory" as far as it "can go")
and yeah, I get it that you think this all sounds CRAZEE; nonetheless, I believe I have a candidate for who he was for the second split in his "prior" incarnation
and will test drive my theory, sit on it for a spell -- the astrology so far so good
but yeah . . . a "dual split"
so if it passes my "tests", then I will post the who and the "why"
